Imagine this. You’ve just added your favorite shoes to an online cart. You tap “Buy Now.” The screen flickers. Within two seconds, it confirms: “Payment Successful.” Simple, right? But what if I told you that behind that one tap is a fast-paced digital relay race—one that determines whether you get your shoes, or a payment failed notification? Welcome to the hidden world of payment gateways. At its core, a payment gateway is the tech bridge between your business and the banks. It encrypts data, validates the card, talks to processors, and returns an instant “approved” or “declined” result. It does all this in under 3 seconds. But that’s just the surface.

A Segment Tree is a data structure that stores information about array intervals as a tree. This allows answering range queries over an array efficiently, while still being flexible enough to allow quick modification of the array. This includes finding the sum of consecutive array elements a[l... r], or finding the minimum element in a such a range in O(log n) time. Between answering such queries, the Segment Tree allows modifying the array by replacing one element, or even changing the elements of a whole subsegment (e.g. assigning all elements a[l...r] to any value, or adding a value to all element in the subsegment). You are given an array A[], and you want to perform: Range queries: e.g., find the sum, minimum, or maximum in a subrange A[l...r]. Point updates: change a value at a speci…  ( 5 min )

On June 16, 2025, WhiteBIT Coin (WBT) reached a new all-time high of $52.27, following a series of steady price gains throughout the year.

Alright, let me be honest right out the gate: I always thought Vim was just some arcane flex tool for terminal nerds. You know — the kind ThePrimeagen uses at lightspeed while yelling "LET'S GO!" on stream. It looked cool. It sounded fast. But it also looked like a keyboard-induced migraine. Still… I was curious. So I decided to see what the hype was all about. Day 1 with Vim felt like: "How do I quit?" "Why can't I type?" "Oh cool, I deleted the entire line again." It was confusing. It was rigid. It felt like Vim was a gatekeeper, not a helper. I legit thought, "This is just a thing YouTubers use to feel cool." And maybe it is — a little. But I kept going. Somewhere around day 3 or 4, I stopped trying to fight Vim. I started noticing that: The modal editing wasn't stupid — it was intentio…  ( 4 min )

The threats to cybersecurity are occurring at an unprecedented rate, and therefore, security testing must ensure organisational protection. External network penetration testing plays a pivotal role in helping you discover the vulnerabilities that can be used by malicious individuals outside your network perimeter. ** ** ** Public-facing web applications and services ** Automated tools do provide broad coverage; however, complex vulnerabilities are likely to be identified using manual techniques. Both methods offer the most comprehensive evaluation possible. ** ** ** Automated domain scanning, subdomain enumeration, and service fingerprinting are all great reconnaissance techniques that will help uncover meaningful information that will assist us in our next steps in the testing process. ** You will need to consider the exploitation frameworks you select for assessment and develop a careful methodology or protocols for testing the possible vulnerabilities that you exploit. Record all your findings, including steps to reproduce those findings, and document the potential impacts on the organisation's business. ** ** Social engineering awareness training complements technical testing by addressing human vulnerabilities that technical tools cannot detect. Combining network testing with social engineering assessments provides a comprehensive security evaluation. ** ** ** ** ** ** ** Want to improve your external security posture?

Hey friends! 👋 It’s a new week and I’m back with another quick, easy tutorial. This time we’re talking about JavaScript objects. Objects used to confuse me a little. Now I just think of them as mini folders storing related info. Let's break it down. Object? An object in JavaScript is like a shopping cart 🛒. const cart = { 'item-name': 'Laptop', price: 2000, quantity: 1 }; Here: 'item-name' is the key and 'Laptop' is its value: this tells us what’s in the cart. price is the key and 2000 is the value: how much the item costs. quantity is the key and 1 is the value: how many you're buying. So instead of remembering each piece of info separately, you group it all inside one neat object: your cart 🛒. It makes data easy to organise, update and use You can use dot notation: console.…  ( 5 min )

For many students, learning algorithms starts in a classroom, surrounded by whiteboards filled with graphs, loops, and pseudocode. It's easy to assume these abstract concepts exist only for exams or coding interviews. But step outside the classroom, and it becomes clear that algorithms shape far more than academic success—they influence our daily routines, business decisions, and digital experiences in ways we rarely notice. Take your morning commute, for instance. When you open a map app to find the fastest route, it doesn’t just show streets. It runs complex algorithms—like Dijkstra’s or A*—to evaluate traffic, road closures, and travel time. The result?

After you ask, Myriade transforms your plain-English question into SQL, fetches the data, and presents clear results as tables, graphs, or easy-to-understand insights. Using a database about Formula 1 Data security matters, so Myriade comes with built-in privacy: Read-Only Mode: No chance of accidentally editing or losing data. Sample Only: The AI only reads a sample of the results (like a human would) AI — Zero Data Retention: Nothing you query gets stored on the AI providers. Zero Knowledge Protection: Advanced features to hide your sensitive data from AI providers. Myriade isn’t just for basic queries. Here are some practical scenarios you can try: Diagnose a Problem: “Why did sales drop on March 10?” Find What’s Missing: “What key metrics aren’t in our monthly reports?” Shape Your Data: “Make a quick table showing each user’s last purchase.” Check Your Data Quality: “Spot any weird duplicates in billing data.” With Myriade, interacting with your database feels less like coding and more like chatting. myriade.ai.

To set up the CAN filter on an STM8 microcontroller (like STM8S or STM8AF series with CAN capability), you need to configure the CAN filter registers to determine which messages the MCU should accept or ignore. Here’s a structured overview of how to configure the CAN filter: 1. Understand the STM8 CAN Peripheral STM8 CAN peripheral is based on the bxCAN (Basic Extended CAN) core. The CAN filter allows mask-based or list-based filtering. You can filter on standard (11-bit) or extended (29-bit) IDs. 2. Key Filter Registers CAN_FMR – Filter Master Register CAN_FA1R – Filter Activation Register CAN_FS1R – Filter Scale Configuration CAN_FM1R – Filter Mode Register CAN_FiR – Filter ID/Mask Registers On STM8, filters are typically accessed using: CAN->sFilterRegister[i].FR1 (Filter bank register…  ( 4 min )

Hey devs 👨‍💻 I just read a post on CMC that really nailed something I’ve been noticing in my own work: broker models are no longer optional for Web3 infra — they’re the new default. A few years ago, exchanges were just backend pipes for liquidity. Today, they’re go-to-market tools, monetization channels, and sometimes the biggest user acquisition engine you’ll ever plug into. That’s a massive shift for those of us shipping wallets, terminals, or anything API-driven. The WhiteBIT case in the article stood out. Their broker model doesn’t just offer API keys and walk away. It gives: Up to 40% revenue share (that’s real money for bootstrapped teams), Custom terms for different product types (finally, someone who gets that a wallet ≠ a DEX ≠ a terminal), Co-marketing and even user tournaments (which can be more effective than paid ads, tbh), Plus: fast onboarding and solid support — which makes a huge difference when you’re on a tight dev cycle. What hit home most? The article also breaks down the Atani x Kraken use case. Worth reading — it shows how good UX, embedded trading, and real-time commission logic actually improve LTV and retention. Something I’ve seen in my own builds too. Anyway, just thought I’d share. If you're building infra and haven't thought about embedded exchange layers or broker monetization, now’s the time.

Forms are essential in nearly every web application — from login and registration to onboarding and settings. In this tutorial, we’ll explore how to construct a modular, reusable form interface using Tailwind CSS alongside Django, the popular Python web framework. Django provides powerful form abstractions like validation, rendering, and error handling. But the default rendering isn’t styled for modern UI. Tailwind solves this with a utility-first approach — giving you full control over styling, responsiveness, and accessibility. To make Django forms look great with Tailwind, you can: Override default widgets Inject custom CSS classes into form fields Use third-party packages like django-crispy-forms or django-widget-tweaks Here’s how to style a text input manually: from django import f…  ( 4 min )

As frontend performance expectations rise, developers are exploring how to bring systems-level speed to the browser. Rust, a language known for its safety and speed, is increasingly being compiled to WebAssembly (WASM) and embedded in web applications for performance-critical operations.

Rust is known for its blazing-fast performance without a garbage collector and at the heart of that magic lies ownership. For devs coming from languages like Python, JavaScript, or even C++, Rust’s ownership model might feel a little strict at first. But once you get the hang of it, it becomes your best ally in writing safe, concurrent code without worrying about memory leaks or race conditions. Let’s break it down with real-world analogies and simple concepts. In Rust, every value has a single owner—a variable that holds responsibility for it. When you assign that value to another variable, the ownership moves. The original variable is no longer valid. `let book = String::from("Rust Book"); let borrowed = book; // book is moved here // println!("{}", book); ❌ Error: book no longer owns t…  ( 4 min )

Hey dev.to community! In my very 1st post where, I have decided to learn django by building small projects. Here is an update on my progress: Did the initial project setup and created a Products app. Created a Product model with slug field which is generated automatically. With slugs SEO-friendly URLs can be created(will write more about this in future post). Created RESTful endpoints(GET, POST, PUT and DELETE). Create Product serializer. I am amazed by how using a few lines of code these APIs can be written utilising Django REST framework generic views. These generic views simplifies the creation of API endpoints for performing CRUD operations. For example, in this project I have created just two views which handles CRUD operations in few lines of code. ProductListCreateView: Uses generics.ListCreateAPIView to get list of all the products(via GET request) and create a new product(via POST request). ProductDetailView: Uses generics.RetrieveUpdateDestroyAPIView to get a single product(lookup based on slug field), PUT request to update a product, DELETE request to remove a product. Another good thing is, Browsable API provided in DRF. One can interact with APIs, test and debug it. Next, I will be working on Categories of the product, expand CRUD operation to categories and get into django admin interface. Also attached some screenshots of the APIs and code. Complete code available here.  ( 3 min )

Introduction Yes, GraphQL can call REST APIs. In fact, this is a common way to use GraphQL in real projects. It lets you use your existing REST services while giving frontend apps the flexibility of GraphQL. In this article, you’ll learn how to call REST from GraphQL using a very simple and practical method. Many apps already have REST APIs. Instead of replacing them completely, you can wrap those APIs with GraphQL. This lets frontend developers ask only for the data they need, without changing your backend. You get the best of both worlds: Use existing REST endpoints Expose a cleaner GraphQL API to clients We’ll create a GraphQL server using Node.js, and we’ll call a public REST API: https://jsonplaceholder.typicode.com/users/:id This is a fake REST API that returns fake user data.…  ( 4 min )

Now let's dive into how this is achieved using classes in C++. class Student { private: int scores[5]; // Each student has 5 scores public: void input(); int calculateTotalScore(); }; We define a class Student to encapsulate the scores and operations. scores[5] is a fixed-size array holding 5 test scores. input() allows entering the scores. calculateTotalScore() adds up the scores. void Student::inpu…  ( 5 min )

Today, I'm going to share about lazy loading in the Cangjie development language. First, let me explain to the beginner friends what lazy loading is. Lazy loading is called LazyForEach in the code. Judging from the name, you can surely guess that its function is similar to that of ForEach. Unlike ForEach's one-time loading of all data, lazy loading loads data on demand based on the available area of the screen. Moreover, when the content slides out of the screen range, lazy loading automatically destroys this content. Therefore, lazy loading significantly optimizes the performance of the program and greatly improves the user experience. This point has already been compared by Youlan Jun in the ArkTs language. When there is a large amount of data, it is strongly recommended that everyone us…  ( 4 min )

Disclaimer: This content is for educational purposes only. I still remember the launch day of our first progressive web app (PWA). We had tested everything — or so we thought. But when users started pouring in, so did the bugs. Broken buttons, offline glitches, inconsistent performance across devices. It was a nightmare. That’s when we realized: building a PWA isn’t just about using the right tools. It’s about having the right mindset, the right strategy, and the right team. Fast forward to 2025, and the landscape has matured. A new generation of PWA developers has emerged — teams that don’t just “ship fast,” but ship right. They’ve solved the bugs. They’ve squashed the delays. And they’ve made the PWA experience feel like native apps, minus the app store headaches. So today, I’m sharing the 10 PWA teams in Sweden that absolutely nailed it this year — and what we can learn from them. 1. Bluell AB (Stockholm) 2. Netlight Consulting 3. Creuna (Now part of Knowit) 4. Tretton37 5. Monterosa 6. B3 Consulting Group 7. Iteam 8. Cybercom (now part of Knowit) 9. Valtech Sweden 10. Qvik So… What Sets These Teams Apart? 1. They Design for Offline First 2. They Test in the Wild 3. They Use the Right Stack 4. They Automate Everything 5. They Talk to Their Users The Real Lesson? It’s Not Just About Tech You can use React and still have janky transitions. You can follow “best practices” and still miss the mark. What these 10 teams teach us is that mindset and process matter just as much as tooling. They listen. They iterate. They care. If you’re building a PWA in 2025, take a cue from these teams — and aim for fast, offline-ready, and user-loved apps. Or even better, find the right team and let them take the lead. 😉  ( 5 min )

Enumerated fields in data tables have a limited number of predefined values. Filtering conditions on the enumerated field f are often expressed as f =v1 or f =v2 or ...; f !=v1 and f !=v2 and ...; in; or not in. The database has to compare f with n values. When the data table is large, the number of comparisons will be very high, leading to poor performance, and the performance worsens as n increases. If comparisons can be avoided during filtering, performance will naturally improve significantly. esProc’s aligned sequence mechanism can achieve this effect. The following example uses the orders table to demonstrate how to use aligned sequences, and also compares the performance of esProc SPL and MySQL database in calculating conditional filtering on enumerated fields.

Hey Devs! 👋 I recently started learning front-end development under devsync.in, and one of the first things that clicked for me was how powerful CSS can be. HTML gives you the structure, but CSS? That’s where the magic happens — colors, spacing, layouts, and even animations. 🚀 What is CSS? CSS stands for Cascading Style Sheets, and its main job is to style HTML elements. Think of HTML as the skeleton of your webpage, and CSS as the clothes it wears. Hello, World! Hello h1 { color: green; } I personally prefer external stylesheets — it's how I was taught at devsync.in, and it really helps in keeping things clean and scalable. 📐 Understanding the CSS Box Model One of the most important concepts I've learned at devsync.in is the box model. Each HTML element is a box made of: Content Padding Border Margin Think of it like layers from the inside out. 💡 Pro tip: Add this to your CSS reset: * { box-sizing: border-box; } This makes layout calculations much easier! 🧠 Final Thoughts Learning CSS with the support of devsync.in has been a game-changer for me. It’s not about memorizing every property — it’s about building a solid foundation and experimenting as you go. Once you understand the basics, it becomes way easier (and more fun!) to create beautiful web pages. If you're also learning or struggling with CSS, I’d love to connect and share tips.

If you’ve worked in the Microsoft development ecosystem, you’ve likely encountered both .NET and ASP.NET—but do you really know the difference between the two? Knowing when to use which can save your team time, money, and a lot of technical headaches. Let’s break it down in simple terms. 🔍 What is .NET? You can use .NET to build all kinds of applications: Desktop (with WPF, Windows Forms) Web Mobile (via .NET MAUI or Xamarin) Cloud-native apps Console apps APIs Microservices So in short, .NET is the entire framework (or ecosystem) that powers modern applications. 🌐 What is ASP.NET? ASP.NET provides: Server-side web development tools Razor pages & Blazor for UI MVC architecture RESTful API development support Authentication and identity handling There’s also ASP.NET Core, which is the modern, cross-platform version—lighter, faster, and designed for today’s cloud-based apps. ⚔️ ASP.NET vs .NET: What’s the Real Difference? 💡 When Should You Use Each? If you're building a web application or REST API → Go with ASP.NET (preferably ASP.NET Core). If you’re developing a desktop app, mobile app, or background service → Use .NET (and the right toolkit like WPF, MAUI, etc.). If you want cross-platform support, always choose .NET 5+ and ASP.NET Core over legacy frameworks. 🚀 Final Thoughts At ChampSoft, we help teams harness the full power of .NET technologies to build scalable, secure, and future-ready solutions. 👉 Read ChampSoft All Blogs: ChampSoft Blog  ( 4 min )

Kubernetes has become a foundational platform for deploying containerized applications. But as more stateful workloads enter the cluster — like databases and shared storage systems — ensuring data protection becomes critical. This no-code guide explores how to back up and restore Kubernetes block and file volumes, the differences between storage types, and best practices for business continuity and disaster recovery. 📌 What Is Kubernetes Volume Backup & Restore? Block Storage: Raw devices formatted by applications (e.g., for databases). File Storage: File systems shared between pods (e.g., for media files or documents). Backup and restore in this context means protecting this stored data from loss, corruption, or accidental deletion — and recovering it when needed. Understanding your stor…  ( 4 min )

Harmony OS Next Object Arrays: Data Updates and UI Refresh Introduction Object arrays are an extremely common data structure in programming, efficiently storing and processing sets of related objects. In HarmonyOS Next, this data structure has widespread applications. For example, when developing a simple contact management application, we can use an object array. Each contact is an object containing properties like name, phone number, and email. For instance: [ {name: 'Zhang San', phone: '123456789', email: 'zhangsan@example.com'}, {name: 'Li Si', phone: '987654321', email: 'lisi@example.com'}, ] This object array structure facilitates operations like traversing, searching, adding, and deleting contact information, enabling efficient contact management.

Introduction: In this post, I’ll explore how Microsoft's Copilot strategy might be the root cause, and why this issue goes beyond just a performance glitch. We’re talking about a larger systemic problem that could have far-reaching implications. Copilot's Impact on Traffic: Microsoft’s decision to embed Copilot across all of its products—from Windows to Office tools—has caused a massive increase in the backend traffic directed to OpenAI’s servers. The issue isn’t just that Copilot is working; it’s that its presence in nearly every Microsoft product is consuming far more resources than anticipated. When you open Notepad or start a simple task in Excel, Copilot might be quietly running in the background, sending requests and consuming resources without you even realizing it. This unseen traf…  ( 5 min )

Leverage: The Promise of Big Gains with Little Capital Leverage trading sounds like a fast lane to profit. Put in a small amount, borrow the rest, and ride a 10× position to a fat payday. Crypto platforms love to flaunt this feature—just a few clicks and you’re controlling thousands of dollars' worth of Bitcoin or ETH. At its core, leverage trading means borrowing money to increase your position size. You commit a portion of your capital (called “margin”) and borrow the rest from the exchange to make a larger trade than your funds would normally allow. To open a leveraged position, you need to provide an initial margin—your skin in the game. Exchanges also enforce a maintenance margin, the minimum equity you must maintain to keep your trade open. You use $1,000 as margin to open a $10,00…  ( 6 min )

In the early days of computing, non-volatile memory was essential for bootstrapping a system. Among the earliest technologies used for this purpose were EPROMs (Erasable Programmable Read-Only Memory), which allowed firmware like BIOS to be stored in a non-volatile yet modifiable format. As computing evolved, so did memory technologies, leading to the widespread adoption of EEPROMs (Electrically Erasable Programmable Read-Only Memory) and flash memory in modern personal computers and embedded systems. This article explores the critical role EPROMs played in early operating systems and how their legacy has transformed with modern EEPROM technologies. EPROMs were a significant breakthrough in the 1970s and 1980s, providing a non-volatile memory medium that could be programmed with a high vol…  ( 7 min )

Ever wonder why some developers ship features while others struggle with endless meetings and Slack pings? The secret isn't working longer—it's working deeper. Last month, I show interview of 15 senior engineers from companies like Netflix, Stripe, and Shopify. One pattern emerged across every conversation: they all protect sacred blocks of uninterrupted time. Not 25-minute Pomodoros. Not "quick focus sessions." Two full hours of pure, distraction-free development. The results? One Staff Engineer told me he ships more code in his 2-hour block than most devs do in an entire day. Another said it's the difference between being a "ticket-taker" and an actual problem solver. Here's how they do it—and how you can replicate their system starting tomorrow.

Introduction If you've ever browsed AWS EC2 instance types and found yourself staring blankly at names like m5.large, c6g.xlarge, or r7a.2xlarge, you're not alone. At first glance, these names can feel cryptic—like trying to decode a secret code. But here's the good news: there's a method to the madness. Each part of an instance type name tells you something important about the underlying hardware, performance characteristics, and intended use case. In this blog post, we'll break down the structure of AWS instance type names and show you how to read them like a pro. Once you understand how to interpret each component, you'll be able to confidently choose the right instance for your workload—and maybe even impress your colleagues with your cloud fluency. Every AWS EC2 instance type name i…  ( 6 min )

Hello, Today, I took a lecture from freecodecamp.com's Full Stack JavaScript course and learned about memory management. When a variable is created, it retains its memory address. function createLargeArray() { let printArrayLength = createLargeArray(); This snippet demonstrates that although createLargeArray() can't be trashed, it is still closed, and the return access means that more memory is used than expected.  ( 3 min )

LeetCode 2966 | Medium | Greedy + Sorting You are given: An integer array nums of size n (where n is a multiple of 3) A positive integer k Your task is to divide nums into n / 3 arrays of size 3, such that in each group, the difference between the maximum and minimum elements is at most k. Return: A valid 2D array of groups if possible. Otherwise, return an empty array []. Multiple valid answers are allowed. We need to split the array into triplets where max difference ≤ k. The optimal approach is: Sort the array: close values come together. Greedily pick every 3 consecutive elements. If the difference between the 1st and 3rd in any triplet exceeds k, it's invalid. This ensures we get the smallest difference across every triplet and maximizes the chance of valid grouping. class Solution…  ( 5 min )

The Serverless Paradox: How Hybrid Architectures and AI/ML are Taming Cold Starts and Vendor Lock-in Serverless computing has emerged as a transformative paradigm in modern application development, promising unparalleled agility, scalability, and cost efficiency. By abstracting away the complexities of infrastructure management, serverless allows developers to focus purely on writing code, with cloud providers dynamically managing resource allocation and scaling. However, this revolutionary approach isn't without its inherent challenges, often referred to as the "Serverless Paradox." Two prominent issues persistently faced by serverless architectures are cold start latency and the risk of vendor lock-in. Cold start latency refers to the delay experienced when a serverless function is inv…  ( 8 min )

In ITConnect, companies aren’t just passive observers — they actively post jobs and look for talent. To support their workflow, we built a dedicated Company Dashboard designed for simplicity, control, and speed. Here’s what we focused on during its development: Key Features of the Company Dashboard Add New Job Postings Manage Existing Jobs View Applicants for Each Job Technical Implementation Built with PHP and MySQL Each job is tied to a company’s unique ID in the database Secure job posting forms with input validation Session-based access control to ensure companies see only their own data Lessons Learned Structuring database relationships is key for efficient application tracking CV files must be easy to access, but protected from unauthorized viewing Keeping the interface simple helps employers stay focused on recruitment The Company Dashboard is designed to be more than just a feature — it’s a daily workspace for companies hiring in tech. We're actively improving it to support more complex needs as the platform evolves.  ( 3 min )

At ITConnect, job seekers are at the heart of the platform. Our goal has always been to give them a clear, functional space where they can manage their profile, apply for jobs, and grow professionally — all from one place. That’s why we built the Worker Dashboard, a secure and focused panel for users with the “worker” role. What Users Can Do in the Dashboard Upload Their CV Add Education and Background Info Apply for Jobs Role-Based Access Control Technical Stack Behind It PHP + MySQL – backend logic and data storage Session handling – to identify logged-in users and enforce access rules Form validation & file upload security – for safe input handling HTML + CSS – for a clean, accessible user interface Key Lessons Learned CV Uploading: Requires strong validation (file size, format, naming) Application Logic: Needs checks to avoid duplicates or spam Access Control: Must be enforced at both front-end and back-end levels The worker dashboard is more than just a user panel — it’s a personalized space where real opportunities begin. We’re continuing to improve the experience based on user feedback and usage data.  ( 3 min )

Falling Into the CSS Rabbit Hole (Yes Again), Cleaning Up EC Links, and Planning Visual Improvements Today didn’t go quite as planned, but I still managed to check off a few important tasks. Yet Again, Stuck in CSS Tweaks Most of my time was unsurprisingly eaten up by CSS. I got caught up in adjusting the finer details of the design and before I knew it, hours had passed. It’s easy to fall into that CSS rabbit hole, but there’s something satisfying about refining the look and feel. Even small improvements can make the whole site feel more polished. Cleaning Up EC Links I took some time to clean up and reorganize the multiple EC links I had scattered across the site. It’s still a work in progress, but I’ve started creating a more consistent and intuitive user flow. Better structure means less confusion for the user, and that’s a win. Added New Pages from the Footer I created placeholder pages linked from the footer. There's no real content yet, but having the basic structure in place is a helpful step toward shaping the full site architecture. Sometimes, just laying the foundation helps bring clarity to what comes next. Next Up: Visual Improvements Right now, aside from the hero section, the site is pretty bare when it comes to images. To boost visual appeal, I’m planning to add more photographs and graphics. I’ll be experimenting with placement using the Z-pattern layout, which helps guide the viewer’s attention more naturally across the page. In Summary It wasn’t the most productive day in terms of raw output, but I did a lot of thinking and groundwork. Progress is progress—even when it feels slow. If you’re in the middle of building something too, hang in there. It’s all part of the process. Date: June 17, 2025 tags: portfolio, webdev, copywriting, ux, learning  ( 3 min )

After weeks of planning and designing, we finally made the big move — we started building ITConnect, our platform aiming to connect job seekers with companies in the tech world. We began by translating our interface from Figma into real, working code. But as anyone who has gone through this process knows, the transition from design to development comes with a whole new set of decisions and challenges. Week 1: Setting the Technical Foundation Creating the initial project layout Designing the navigation, footer, and main page sections Building a login system that supports two user types: companies and job seekers Setting up a database with key tables (users, companies, jobs, projects...) Implementing a file upload system for CVs and profile images Our Team & Workflow Erzana – backend logic and database structure Sumea – frontend development, bringing the Figma design to life Isme – authentication and platform security We collaborate daily using: GitHub for version control Discord for communication phpMyAdmin for managing the database Early Challenges & Lessons Learned Handling multiple user roles in a shared login system Securing access to pages based on user type Validating user input and profile data Safely storing uploaded files These problems helped us grow technically and work better as a team. What’s Coming Next? Building a company dashboard to manage job listings and applications Creating a worker dashboard for profiles and CV management Adding a section for freelance project applications Integrating a calendar feature for interviews and meetings We’re excited to keep sharing our progress and the lessons we’re learning along the way!  ( 3 min )

After carefully completing our project design in Figma, we thought the hardest part was behind us. But as soon as it was time to turn the design into a working product, we faced an unexpected challenge: We weren’t sure which technical direction to take. Each of us had different ideas. Some preferred a simpler and more straightforward approach, while others suggested a more modern and flexible solution. We spent time discussing, weighing the pros and cons of each option. What we learned is that this phase of the project requires not just technical knowledge, but also teamwork, compromise, and a shared vision of what we’re trying to build. In the end, we made a decision that felt right for us—as a team and for the goals of the project. In the next post, we’ll share more about the implementation process and the lessons we learned along the way.  ( 3 min )

At 8 PM, I was plating the second-to-last course of a wine dinner for 70 guests. At 3 AM, I was spinning up virtual machines and tearing apart old laptops. I’ve been cooking for as long as I can remember. When real life hit, I jumped straight into the kitchen — and almost never looked back. I tried a few other jobs here and there, but nothing ever really stuck. They paid the bills, sure, but they didn’t interest me. Cooking, though? I had the skills. I could make decent money doing it, and I loved it — so dealing with the chaos and the long hours felt worth it. But somewhere in the middle of all that, something shifted.

How we turned our idea into an interactive and intuitive user experience. When we started building ITConnect, we didn’t just want a platform that works. And that’s where design comes in. From Idea to Interface How can a student quickly find a job or a freelance project? The Home Page: The First Impression At the top, we placed a Hero Section with: A bold statement of our mission Testimonials from students who’ve found work and companies who’ve found talent — real success stories that build trust. Two large cards/buttons: Company Dashboard — Smart, Searchable, Simple A search bar with filters by skills, location, experience, and programming languages A profile page that includes: “Recommended for You” section — suggestions based on activity and profile Collaborate in real-time, no matter where we were What’s Next? But Figma isn’t done yet — as we grow, we’ll keep testing, adjusting, and iterating our UI based on real user feedback.

A student-driven project aiming to bridge the gap between young IT professionals and the companies that need them. Technology is not just code and algorithms. It’s opportunity. It’s connection. This is our idea. And this is our story. Why did we decide to create this platform? At the same time, companies are looking for talent — developers, designers, network engineers — but often don’t know where to find them easily. So, we asked ourselves: What if there was a simple, smart platform that connects both sides efficiently? What is ITConnect? IT talents (students, junior devs, freelancers) can build profiles, apply for jobs or projects, and grow their careers And we’re proud to say: this is being built by three Albanian students, from the ground up.  ( 3 min )

在发布我们的 SDK 时，一个时常需要考虑的问题：我们的新版本 SDK 应该支持哪些“版本”？ 这里的“版本”指代很多的东西，比如： 哪些型号的硬件，如 Intel vs Apple M 或者有没有 LiDAR 和 GPS 的设备 最低的可以用于开发的 macOS 版本 最低的可部署的 iOS 版本 最低可用于开发的 Swift 编译器以及 Swift API 对应的版本，如 4.3，5.0，6.0 等等 …… 作为苹果开发者很幸运：苹果公司和 macOS 已经尽量流线化整条产品线，作为苹果开发者毋需过多关注产品的兼容性——想想过去的 Windows 开发者要一直后向兼容到 Windows95，或者 Android 开发者不仅要兼容到 Android 4.0 还要在各种奇形怪状、性能高低的设备上测试，就庆幸自己手上的活儿已经足够简单；但发布时需要考虑的版本矩阵、排列组合，倒也并非一目了然。 苹果官方文档在这个页面上列出了对应的版本匹配，以方便专业开发者更好地厘清版本号的关联：https://developer.apple.com/support/xcode/ 对于我们 SDK 而言，大体上的策略是每年 iOS 升级为版本 n，则兼容 n, n - 1, n - 2 三个版本。而 Xcode 基本目前也是一年一个大版本号，我们也就秉承着“新的 major 版本 Xcode n.0 发布后的我们 SDK 的第一次更新，升级至要求当前 Xcode n.0 大版本”这样的策略。 这几乎已经足够简单明了，但还是有个小的不足—— 由于 Xcode 每年发布一个 major 大版本后 (Xcode 16.0)，通常有四到五次 minor 小版本的更新 (Xcode 16.1 - Xcode 16.4)，这就要求我们随时跟进 Xcode 更新，确保新的工具链依旧能开发、编译 SDK。同时，还要确保支持的最低版本 Xcode，不会因为 SDK 误用新引入的功能，而无法依赖引用它。因此，团队里几乎每一个开发者，都要安装至少三个版本的 Xcode： Minimum requirement version, e.g., Xcode 16.0 (16A242d) Current released version, e.g. Xcode 16.3 (16E140) Next beta version, e.g., Xcode 16.4 Beta (16F1t) (Before WWDC) or Xcode 26.0 Beta (17A5241e) (after WWDC) 有时，因为切换 Xcode 版本失误，会有不兼容的 API 符号溜进代码里面。好在有重重把关，总有人能在发布前测试发现这样的问题，确保发布的 SDK 不会在某些我们号称支持的版本上不能用。 然而，还是有点儿后怕——如果版本号的问题从 SDE 和 DevOps 眼皮底下都溜过去，最终被用户碰到，也算事故了。除了给每一台部署和测试的机器都装上三个版本的 Xcode，留一堆各种版本 iOS 的测试机以外，还能有什么更好更灵活的办法，来质检版本号呢？🤔  ( 3 min )

Cloudflare has announced an update to the enforcement order of its Gateway policies, rolling out progressively between July 14th and July 18th, 2025. The email from the Cloudflare Gateway Product Team explains that while this update will not weaken your security posture or change the traffic filtered by your policies, it does require a review of your configuration—particularly if you have HTTP policies in place. In the current model, Cloudflare Gateway evaluates DNS, then HTTP, and finally Network (Layer 4 Firewall) policies. After the update, the order will change to evaluate DNS first, followed by Network policies, and then HTTP policies. For example, if you have an HTTP policy that shows a block page for a “SaaS application” and a corresponding Network policy that silently blocks traffi…  ( 5 min )

We set out to build a system that could generate and run end-to-end tests automatically with predictable results and minimal input from the user. No recorded flows, no screenshots, no manual setup, just a URL. The system scans the page, builds a structured view using a serialized DOM, and generates test cases based on what it finds. We initially approached UI testing as a reinforcement learning (RL) problem. The idea was to train an agent to “see” a rendered web page: locate input fields and buttons based on screenshots, and act as a human user would. We fed screenshots into an RL model so it could learn where fields and click targets were. After a few iterations into the RL research, we began building a visual dataset and training a multimodal model that combined raw HTML (as text) with c…  ( 7 min )

When building backend APIs with Node.js—especially with frameworks like Express or NestJS—you’ll often find yourself handling user input via req.body, req.query, or req.params. But here’s a subtle trap many developers fall into: Mutating the request payload directly can cause hidden side effects. In this post, we’ll explore: What those side effects are, How Express and NestJS treat the request payload, When you should deep copy the payload, And best practices for safe and predictable request handling. When you mutate req.body, you're changing the original object passed through the entire request pipeline. This introduces side effects—unintended consequences in other parts of your app. // Middleware A req.body.username = req.body.username.trim().toLowerCase(); // Middleware B if (req.body.…  ( 4 min )

🚀 Automate EC2 Web Server Deployment on AWS with Terraform and Remote S3 State Managing infrastructure manually is error-prone and inefficient. In this project, I use Terraform to automate the provisioning of an EC2 instance that serves a static website — with terraform state pushed to S3. This Terraform project sets up: ✅ An EC2 instance ✅ Security Group allowing HTTP & SSH ✅ User-data to install and serve a website ✅ S3 bucket for Terraform state storage ✅ IAM Role & Policy for EC2 access to S3 terraform-ec2-web-s3/ ├── ec2.tf # EC2 instance + User data ├── iam.tf # IAM role and policy for S3 access ├── outputs.tf # Useful outputs ├── provider.tf # AWS provider config ├── s3.tf # S3 bucket setup ├── securitygroup.tf…  ( 4 min )

While Vercel only provides packages with the component for Next.js, Nuxt, and Astro, you can enable Image Optimization in any framework with the Vercel Build Output API. The first thing we need to do is tell Vercel that we want to use the Image Optimization API. To do that, we need to modify the bundler to add additional parameters to the .vercel/output/config.json file after the build. TanStack Start uses Nitro under the hood, and it provides an easy way to do this. All you need to do is create the nitro.config.ts file with the following content: export default defineNitroConfig({ vercel: { config: { images: { domains: ["yourdomain.example.com"], // Change to your domain sizes: [ 16, 32, 48, 64, 96, 128, 256, 384, 640, 750, 828, 1080, 1200, …  ( 4 min )

Developing iOS applications typically involves languages like Swift or Objective-C. However, with the advent of Rust, a systems programming language known for its safety and performance, and UniFFI, an interface generator for Rust, it's now possible to create iOS apps in Rust. In this blog post, we'll guide you through the process of building a simple iOS app using Rust and UniFFI. Before we begin, ensure you have the following installed: Rust: Install it from the official Rust website. Xcode: Available on the Mac App Store. Start by creating a new Rust library. cargo new app --lib Add uniffi to your Cargo.toml file: [lib] crate_type = ["cdylib", "staticlib"] name = "mobile" [dependencies] uniffi = { version = "0.25.3", features = [ "cli" ] } Change your lib.rs file.

A psychologically-aware Claude is a safer, clearer Claude. I injected a 7-number psychology vector (≈ 50 bytes) into Claude Sonnet’s system prompt. It boosted empathy, risk calibration, and action clarity. In a blind A-B, Claude preferred the vector reply 12-1 (plus one tie). See screenshot for before-after responses and σ-scores. Receptiviti’s API returns 200 quantitative signals for any chunk of text. For this demo I used just seven: emotional awareness risk tolerance conscientiousness analytical thinking affiliation drive openness authenticity Those numbers are normalised (−1 σ to +1 σ) and squeezed into one comma-separated line: [psyvec: -0.2,+0.8,+0.4,-0.5,+0.6,-0.1,+0.3] Place that directly after your system role. It costs virtually zero extra tokens at inference time. • Gemini-style went from generic to empathy-tuned reply Plug-and-play: no model fine-tune, no extra GPUs, works in any prompt flow, vector replies felt more personal Capture ~350 words of user text. Send it to /analyze on the Receptiviti API. Select a subset of salient measures (start with the seven above). Build a psyche vector string and prepend it to your next Claude call.  ( 3 min )

What is git? Git is a distributed version control system, which means that a local clone of the project is a complete version control repository. These fully functional local repositories make it easy to work offline or remotely. Developers commit their work locally, and then sync their copy of the repository with the copy on the server. This paradigm differs from centralized version control where clients must synchronize code with a server before creating new versions of code. Version control, also known as source control, is the practice of tracking and managing changes to software code. Version control systems are software tools that help software teams manage changes to source code over time. As development environments have accelerated, version control systems help software teams wo…  ( 4 min )

Developers deserve to have fun. There was a time when the internet felt magical. I remember going to the library just to create a character on The Doll Palace. At home, I'd spend hours changing fonts with WordArt. But as I grew up, the industry did too. We've shifted away from marquees and glittery cursors. Grown-up me started using ones and zeros to build reliable systems for insurance, banking, and healthcare companies. There's pride in that, but it's harder to justify doing something just because it's fun. That's why I tapped into my inner child and used Goose to build a UI that reacts to users' emotions. Sometimes I want to write every line of code. Other times, I just want a quick dopamine hit from seeing my idea go from vision to execution in minutes. Other developers may relate to t…  ( 6 min )

Working on a client project in a distant country recently presented an interesting challenge. They had a strict requirement, I needed to upload my progress every week so they could monitor the project in real-time. I agreed, though with some initial reluctance. This setup quickly revealed unexpected bugs whenever I moved my code from my local development environment to the live server. One particular issue left me truly dumbfounded: the PHPMailer-powered "send mail" feature worked flawlessly on my local machine, but consistently threw errors on the live server. The solution was simple once identified: I had to rename the PHPMailer folder on the live server to match the exact capitalization used in my require statements. Once I changed it to PHPMailer, everything worked perfectly. If you ever encounter similar "file not found" errors when deploying from a Windows to a Linux environment, always ensure your file and folder naming conventions are precise and consistent down to the capitalization. Adhering to conventional naming standards across both servers will save you countless hours of debugging and a lot of stress.  ( 3 min )

For developers raised on NetBeans, the transition to a modern, AI-first IDE like Cursor can feel like stepping from a familiar kitchen into a spaceship. Cursor is fast, sleek, and intelligent—but also minimalist and opinionated in ways that can clash with long-ingrained workflows. While the benefits are real—AI-powered autocomplete, a VS Code ecosystem, and blazing performance—getting there isn't frictionless. Here’s a breakdown of the challenges you might face when trading the old-school reliability of NetBeans for the cutting-edge world of Cursor. If you’ve used NetBeans for years, you’ve developed more than preferences—you’ve built instincts. Cursor strips much of that away. NetBeans offers rich GUI interfaces for almost everything: running tests, inspecting services, managing databases…  ( 5 min )

"Your database is a ledger, not a scrapbook." Most apps treat data like a blackboard—constantly erasing and rewriting. CRUD (Create, Read, Update, Delete) is simple… until: You need to audit changes ("Who set this price to $0?") You want to replay history ("How did the system behave last Tuesday?") You accidentally overwrite data with no recovery path. Event Sourcing flips the script: Instead of storing state, you store events that led to that state. But when does it actually matter? Let’s compare. 1. The Core Difference CRUD (Traditional Rails) # Update a user’s balance directly user.update!(balance: 100) # Problem: History is lost # What was the balance before? Who changed it?

Ok so I've now been using Claude Code for a little over a week. It has supplanted Cursor as my primary tool for AI assisted coding tasks, and the transition was very rapid. In fact, I'm not sure I'm going to continue to pay for Cursor. One of the things that I discovered early on with Cursor was that it would frequently get "lost" in my monorepo. If it ever wanted to run an external command, such as installing another npm dependency, it would do it in the wrong directory (usually the repository root). The same thing would happen when trying to run the linter, or unit tests, etc. Almost every single time, I had to explicitly tell it to run a command in a given subdirectory, or just reject the command altogether and run it myself. To address this problem, I began running searpate Cursor in…  ( 7 min )

Backend Developer, you've probably had this situation happen: You finish building your API. Everything works perfectly. You test it ten times on Postman. Then your Frontend Developer shows up frustrated: “Something’s not working... the app is freezing!” You check the code and see that your API always returns 200 OK, even when there's an error — with a JSON message saying "Something went wrong." Meanwhile, the frontend is expecting something like 400 Bad Request to show an error message properly. You're both speaking JSON… but you're not speaking the same language. HTTP Status Codes come in. HTTP status codes are standardized codes sent by the server to indicate the result of a client's request. They aren't just random numbers. They're the core communication language between frontend and ba…  ( 5 min )

You're building with AI — maybe a chatbot, an agent, a writing assistant, or something more experimental. The code is coming together, the idea is taking shape… and then the real question hits: “Which model should I actually use?” Suddenly, you’re lost in a jungle of names: GPT-4, GROK, Mistral, Claude, LLaMA, Gemma... Some are open source. Some are locked behind APIs. Some are fast, others smart, all of them marketed like they’re magic. And every source seems to offer conflicting advice. The truth is: It’s not about picking the best model in the world — it’s about picking the best model for your job. This post is a practical, developer-focused approach to making smart model choices — without the confusion, wasted resources, or marketing noise. It’s inspired by Chip Huyen’s book, AI Engin…  ( 6 min )

From clean code to clean systems — my journey into system design and the architectural insights that changed the way I build. At the end of May, I made a conscious shift in my learning journey — I dove deep into System Design. It became clear that writing clean, scalable, and maintainable code goes far beyond just knowing a language or framework — it starts with how your entire system is designed. I’ve always believed in the cycle of learn–unlearn–relearn. So I paused, re-evaluated, and redirected my focus toward understanding: What is system design? Why does it matter? When do we need it? This shift opened my eyes to the architectural thinking behind every successful product. I started with: Architecture patterns PRD (Product Requirements Document) — understanding how clear documentation shapes the development lifecycle. Next came Microservices Architecture — and that’s when things got exciting. I explored: Architectural styles and service boundaries API Gateway and NGINX for routing, load balancing, and security The role of asynchronous communication in system performance Version control and project organization also matter. I studied: Monorepo: Single repository for all services/projects Polyrepo: Independent repositories for each service/module Both have their strengths. Knowing when to use one can streamline collaboration and CI/CD processes. I wrapped up with: RBAC (Role-Based Access Control) to structure user permissions ERD (Entity Relationship Diagrams) to visualize data models and relationships across the system To build systems that are clean, efficient, and easy to evolve. System design is helping me see how everything connects — from requirements to deployment. And I’m just getting started. 💬 Are you also diving into system design? Share your experience or favorite resources in the comments! 📌 Connect with me on DEV — that’s where I’ll be documenting the journey further.  ( 4 min )

Introduction In JavaScript, it's common to interrupt processing using throw for error handling. While this enables a form of non-local exit, TypeScript lacks the ability to statically type these thrown errors, compromising type safety. To address this, the Result type offers a way to explicitly model success and failure in a function's return value. Libraries such as neverthrow, effect-ts, and fp-ts are commonly used to introduce this pattern into TypeScript. However, each of these libraries has trade-offs. While neverthrow is relatively simple and user-friendly, it is no longer actively maintained—many pull requests have been left unreviewed for months. On the other hand, effect-ts and fp-ts offer powerful features but come with high complexity and large bundle sizes, which can be overk…  ( 4 min )

Anchoring is one of the most critical aspects of boating, especially for adventurers who explore diverse waters. But what makes the process smoother and more efficient? One key component: the bow roller. 🛥 What Is a Bow Roller? A bow roller is a metal or polymer fitting mounted on the bow of a boat, designed to guide the anchor rode and anchor chain during deployment and retrieval. It allows your anchor to move freely without damaging the boat or creating friction on the hull. 🔧 Types of Bow Rollers Single Bow Roller – Ideal for smaller boats or occasional anchoring. Double Bow Roller – Allows dual-anchor setups. Self-Launching Bow Roller – Uses gravity and angles to deploy the anchor with minimal effort. Adjustable Bow Roller – For larger vessels needing multi-position adjustment. 🔍 Pro Tip: Always choose a roller that suits your anchor type (Danforth, Bruce, Plow, etc.) 🌊 Why Bow Rollers Matter Prevents anchor chain damage to the hull Eases anchor retrieval with windlasses Enhances anchoring safety during rough waters Keeps the anchor secure and stable when underway 🛠 How to Install a Bow Roller Choose a marine-grade stainless steel or aluminum roller. Align the roller with your anchor locker and chain path. Secure it using corrosion-resistant bolts and marine adhesive. Test it with your anchor before hitting the waters. ** Best Bow Rollers for 2025** Lewmar Bow Rollers Mantus Marine Anchor Rollers Sea-Dog Line Bow Rollers These brands offer durability, design flexibility, and compatibility with different anchor types.  ( 3 min )

BioChatter is a new open source Python package (v0.11.1 released June 6 2025) designed to bring conversational AI into biomedical research workflows. This library provides a clean backend interface for integrating large language models with biological knowledge graphs via BioCypher and common biomedical tasks. It abstracts away provider specific details with a unified API for sending prompts, retrieving structured outputs, and handling model completion logic over multiple LLMs. Install the package via pip: pip install biochatter Then initialize and call a model: from biochatter import BioChatter bc = BioChatter(provider="openai", api_key="YOUR_KEY") response = bc.ask("List key genes involved in oxidative stress response") print(response) BioChatter converts your question into a structured query, invokes an LLM, and formats the response as JSON or a DataFrame. It also supports: integration with BioCypher for knowledge graph grounding evaluation metrics such as accuracy and F1 for test sets model agnostic chaining to compare GPT 4, LLaMA, and others BioChatter streamlines building apps like gene disease extractors, literature summarizers, or dialog agents for molecular data without scaffolding each component manually. The built in evaluation framework lowers the barrier for reproducible benchmarks in biomedical NLP. Researchers working on hypothesis generation, clinical extractive tasks, or biomedical QA now have an easy way to prototype and compare conversational AI pipelines. Explore documentation and examples at the GitHub repo. Start experimenting by connecting to your lab’s knowledge graph or loading custom biomedical prompts. Share your use cases and help grow the community. BioChatter lays the foundation for more conversational and data driven tools in biology, offering a versatile core for integrating LLMs thoughtfully into scientific workflows.

For years, Cloudflare’s WAF has been my go-to solution for protecting web applications. It’s easy to use, has strong threat intelligence, and offers features like rate limiting, bot mitigation, and challenge pages. However, it’s not without downsides—especially for those of us who prefer control, transparency, or simply want to avoid recurring costs. Recently, I set out to find a self-hosted alternative that could meet my needs without compromising on protection. After testing several options, I discovered SafeLine, a powerful, open-source Web Application Firewall that has now fully replaced Cloudflare WAF in my stack. Here’s how and why.

The Map state of AWS Step Functions returns an array of arrays as a result. For further processing, we often need to flatten this result into a simple one-dimensional flat array. With JSONPath, this can be accomplished using the [*] expression as described in the AWS docs: "ResultSelector": { "flattenArray.$": "$[*][*]" } AWS docs for JSONPath Recently, AWS Step Functions introduced JSONata as an alternative query language to JSONPath. However, since this feature is quite new, you won't find much information on how to accomplish the same with JSONata. At least, this section didn't make it into the AWS docs for JSONata yet. In JSONata you can use the .* expression to flatten an array of arrays: JSONata Exerciser However, you must be aware that this expression returns nothing if the result array is empty: JSONata Exerciser In JSONata, you can usually append [] to an expression to cast the result to an array, even if it has only one value: JSONata Exerciser However, this trick doesn't work in this case as both [].* and .*[] will return nothing: JSONata Exerciser The correct way to handle it is a simple ternary condition using the $exists() function: JSONata Exerciser If the expression $exists(states.result.*) evaluates to nothing (falsy value), it will return an empty array as a fallback. You may ask yourself if there is a shorter version using a short circuit || or null coalescing ?? operator like in JavaScript: states.result.* ?? []. Unfortunately, this remains an open issue.  ( 3 min )

Next day's focus was all about TypeScript, and it opened up a new way of thinking about code for me. I’ve always been comfortable with JavaScript, but this statically typed superset challenged me in a good way. We started by covering the basics — type annotations for variables, function parameters, and return values. Then we moved into more advanced concepts like interfaces, type aliases, and optional vs required properties. It felt a little rigid at first, especially coming from JavaScript's flexibility, but the benefits quickly became clear. I built a simple to-do app and used TypeScript to define the shape of each task, enforce valid input, and handle errors gracefully. By the end, my IDE was catching mistakes before I even ran the code — something JS never gave me. That sense of confidence and clarity was super motivating. One thing that stuck with me: “TypeScript makes you design your data before writing the code.” That discipline made my logic cleaner and more reusable. It also made debugging easier because everything was more predictable. I can already tell that TypeScript will be central to how I build both backend and frontend features going forward — and I’m actually excited about that. 💬 Question for Readers: How has using TypeScript changed the way you think about writing JavaScript? Did it help you avoid bugs, or did the strict typing feel like a barrier at first?  ( 3 min )

Leaderboards are everywhere in AI these days. They help us compare models, track progress, and decide which ones are worth our time and resources. But sometimes, a model's top score might raise an eyebrow—almost like it knew the answers ahead of time. It’s easy to assume the highest-ranked models are the smartest or most capable. But in reality, there’s a subtle issue that can throw these rankings off. And while it might sound like cutting corners, it’s not always that simple—or even wrong. In this article, we’ll take a closer look at how this issue impacts model evaluations, why it’s more common than you might think, and how, when handled carefully, it can actually make models more useful in practice. Think of training an AI model like preparing a student for an exam. Now imagine if that …  ( 5 min )

Passing argument by object reference, you will not understand in coding level it more of memory thing how memory work for passing an argument I will give you two example from python and C. Creating my_box: Python creates a dictionary {"item": "old toy"} at some memory address, say 0x1234. my_box is a variable that holds the reference 0x1234 (the address of the dictionary). Calling change_box(my_box): The function change_box gets a copy of the reference 0x1234, stored in its parameter box. Now, both my_box (outside) and box (inside the function) point to the same dictionary at 0x1234. 3.Modifying the Object: When box["item"] = "new toy" runs, it modifies the dictionary at 0x1234. Since my_box still points to 0x1234, it sees the change ({"item": "new toy"}). What If We Reassign? (Uncomment the line): If you uncomment box = {"item": "another box"}, Python creates a new dictionary at a different address, say 0x5678. Now, box points to 0x5678, but my_box still points to 0x1234. The original dictionary (my_box) remains unchanged. num is stored at some memory address, say 0x1000, with value 10. The function try_to_change gets a copy of num’s value (x = 10) stored at a different address, say 0x2000. Changing x only affects 0x2000, not 0x1000. Passing by Reference Using Pointers I know this topic is complicated, not easy to understand. But please do let me know which part you don't understand. This is easiest way to understand.  ( 4 min )

A website can load its content in a flash, but if users can't click, scroll, or interact with it, the experience feels broken. This delay, known as Time to Interactive (TTI), is often caused by third-party scripts (for analytics, chat widgets, etc.) blocking the main thread. At NextBlock CMS, we're engineering a solution to this problem from the core. We are meticulously auditing every script and using the Next.js component to load them intelligently, ensuring your site becomes interactive as quickly as possible. Our approach uses two key strategies: strategy="afterInteractive" for Essential Scripts: For scripts that are important but not critical for the initial render (like analytics), we use this strategy. It tells the browser to load the script after the mai…  ( 3 min )

Git Hooks are awesome - in theory. They let us: test before doing a commit. ✅ lint code before a push. ✅ prevent interns from crashing production due to untested code 😱 But let's be honest, how many of us really use them huh? Most of us probably don't use them mainly because: They live inside of .git/hooks directory They can't be version controlled Feel like a trap - what if I mess up and do push to production but the hook didn't work and now the entire site crash(maybe that's why the internet is down today?) So, most of us, like me just: Ignore them completely Or if you feel like killing yourself, you code in JS and can just use Husky - Which is amazing but nodejs only Feeling trapped to use node everywhere(even the backend 😱), I decided to write a CLI based tool, GetHooky, to manage al…  ( 4 min )

🎯 Objective Demonstrate how to exploit a blind SQL injection vulnerability when: The application does not return any visible output. Error messages are suppressed or handled gracefully. No conditional response difference is observed. In such cases, we can use time-based blind SQL injection — where the attacker forces the database to wait (delay) for a certain amount of time depending on whether an injected condition is TRUE or FALSE. This delay allows us to infer sensitive data one character at a time based on how long it takes for the HTTP response to arrive. Key Concepts 1️⃣ Blind SQL Injection A type of SQL injection where the attacker cannot see the results of their query. There's no direct output or error message returned from the application. There are two main types:…  ( 5 min )

Last time, we compared LangGraph.js and LlamaIndex.ts to see which framework makes building AI agents in JavaScript easier. Today, we’re going one step further: building a production-ready AI agent backend using NestJS and LangGraph.

Because sometimes, the best way to understand a framework... is to try rebuilding it from scratch. Frameworks are like magic tricks — they look simple on the outside, but try to reproduce one, and you’ll realize just how many hidden mechanisms are involved. Cloning a web framework forces you to confront questions like: How is routing resolved? Where does state live? How is middleware applied? What happens when an error is thrown? Can you express a feature without undocumented coupling? In short: cloning exposes architecture. And architecture, not syntax, is where complexity hides. This list isn’t about how popular or feature-rich a framework is. It’s about how difficult it is to replicate its core logic.

Scenario In my project, we have over 10+ users with access keys. Most of the access keys were 300–400 days old. Having access keys lying around for a long period poses a security risk, which is unacceptable. They’re not just a minor security issue — they’re multimillion-dollar liabilities. The issue I can see is that no one remembers to rotate the access keys, so I thought of building a Lambda function that could remind the team to rotate the keys after a certain number of days. Different organizations enforce varying rotation policies — some require rotation every 30 days, others allow 60 or 90 days before access keys must be refreshed. My solution needed to accommodate these different requirements while being easy to deploy and maintain. In this blog post, I’ll walk you through the com…  ( 9 min )

Caching is difficult to get right and often means you need to pull in additional frameworks into your code. Fine tuning the balance between performance and data freshness takes time and experience. In case of User-Agent integrations (for example, an application UI running in your user’s browser), it is even more crucial, as the User-Agent is rarely under your control and yet demands fast response times. This is why often I opt to provide cache recommendations for the service side in many cases. One such example of this in the product I work heavily with Authress. That doesn’t mean you can’t cache returned values for longer. I'm going to use Authress as example for caching, so a quick summary might make sense. Authress provides login and access control for the applications you write. This m…  ( 9 min )

The Interview That Changed Everything Let me take you back to an interview we had—not long ago—with a candidate whose résumé was an actual masterpiece. MIT grad, five languages, built half the tools your team probably uses. But somewhere between, “Tell us about your last team project,” and “How do you handle feedback?” we realized… something was off. No eye contact. No energy. The moment we brought up clients or communication, the vibe dipped like a bad internet connection. We didn't hire him. It wasn’t about skills. It was about fit. And more importantly—it was about people. At Einfratech Systems, we love a well-structured function as much as the next dev team. But if there’s one thing we’ve learned over the last few years, it’s this: You can train a person to write better code. You …  ( 4 min )

Ever joined a GitHub Enterprise and thought, “Who organized this… chaos?” I created this post because in the last few months I always got the same questions from customers about how they could structure GitHub Enterprise, especially something like: “How many organizations I need to create?” GitHub Enterprise is incredibly powerful — but only if it's structured right. As your engineering org grows, so does your sprawl: multiple organizations, dozens (or hundreds) of repositories, unclear team access, and policies all over the place. The result? Confusion, security gaps, and onboarding pain for every new dev. I’ve seen GitHub Enterprise setups ranging from tightly governed to wild west mode, and the difference usually comes down to one thing: how well the org is structured. This post is base…  ( 6 min )

NEWSARC.io: A New Way to See the World — Perspective on a Timeline Introduction: Have you ever felt like you’re only seeing part of the story? Imagine standing in a room with just one tiny window. Every day, you look through it and see the same view. It becomes familiar — comforting, even — but deep down, you know there’s more out there. That’s how reading the news often feels for me. While trying to understand global events — wars, politics, markets, climate crises — I kept hitting the same wall: limited perspectives, missing context, and headlines that seemed to nudge me toward a conclusion rather than help me form one myself. I didn’t want pre-packaged opinions. I wanted the full picture and to be able to research myself. As a developer (and, let’s be honest, a bit of a news junkie r…  ( 5 min )

What is Recursion? Recursion is when a function calls itself to solve smaller parts of a problem — ideal for tasks that can be broken down into repetitive subproblems. ✅ Basic Recursive Structure def function_name(): # base condition if condition: return something else: return function_name() # recursive call Without a base condition, the function will keep calling itself forever — causing a RecursionError. 💡 Example 1: Factorial Using Recursion def factorial(n): if n == 0 or n == 1: # base case return 1 else: return n * factorial(n - 1) print(factorial(5)) # Output: 120 Here’s how it works: factorial(5) → 5 * factorial(4) → 5 * 4 * factorial(3) → 5 * 4 * 3 * factorial(2) → ... → 5 * 4 * 3 * 2 * 1 = 120 💡 Example 2: Fibonacci Series Using Recursion def fibonacci(n): if n == 0: return 0 elif n == 1: return 1 else: return fibonacci(n-1) + fibonacci(n-2) for i in range(7): print(fibonacci(i), end=' ') # Output: 0 1 1 2 3 5 8 🔨 Mini Project: Factorial & Fibonacci Calculator def factorial(n): return 1 if n <= 1 else n * factorial(n - 1) def fibonacci(n): if n <= 1: return n else: return fibonacci(n - 1) + fibonacci(n - 2) num = int(input("Enter a number: ")) print("Factorial:", factorial(num)) print("Fibonacci:", fibonacci(num))  ( 3 min )

A website passes an automated accessibility scan with flying colors. The dashboard shows zero errors, and you're feeling confident. But when a screen reader user attempts to navigate the site-or someone tries to operate it with a keyboard only-the experience falls apart. Automated accessibility testing tools are useful, no doubt. They speed up checks, catch many critical issues, and help enforce web standards like WCAG. But they’re not infallible. Many nuanced and contextual issues fly under the radar, and relying on automation alone can give a false sense of compliance. To build truly inclusive digital experiences, human insight is essential. Below, we explore 12 real accessibility problems that automated tools often miss-and why it’s vital to complement automation with manual testing. Au…  ( 6 min )

Most B2C app founders assume subscriptions are their golden ticket to revenue. But what if we told you that 70% of a successful social investing app's revenue comes from brand partnerships, not subscriptions? In a recent episode of the Trophy Podcast, we sat down with Tim Johnson, head of brand partnerships at Blossom Social and former partnerships lead at Wattpad (acquired by Naver for $600M). Tim shared how he's generated over $2 million in partnership revenue for Blossom—a seed-stage company—and why brand partnerships might be the overlooked revenue stream your B2C app desperately needs. While most founders obsess over subscription metrics, Tim revealed a startling reality about Blossom's revenue mix: "30% of the revenue comes from subscriptions, which most apps are only half that 30%. …  ( 6 min )

Hey folks! TL;DR: Rive is a big deal for designers, and developers. I've been experimenting with motion design & micro interactions lately. As context, I'm a full stack dev with a background in design & motion. I've always dreamed about a way to make animations in After Effects that are NOT just meant to be exported as .mp4 files but actual interactive animations I could use on my websites or apps. Back in the day, I messed around with Lottie using the Bodymovin plugin for After Effets in order to achieve that. I'm not gonna lie: it "worked" but it was very bad DX and not really efficient (big JSON animation file). -- 5 years later -- I stumbled upon Rive and started to experiment with it, and wow it's exactly what I would dream about: An animation tool that can export lightweight and interactive animations with full control through code. The export is a .riv binary file that is loaded by the Rive SDK. Starting from that, you can interact with your data bindings and inputs set in Rive in plain JS, enabling infinite possibilities! My personal take is that with the incoming flood of average software due to AI, design delight will be back. And this Rive thing is probably a big deal for the future. Let me know your thoughts! Cheers.  ( 3 min )

Senior developers face a productivity crisis. Research shows developers lose 8+ hours weekly to inefficiencies, with only 44% of managers aware of these issues. Context switching affects 43% of developers, while early-career developers doing 15 hours of deep work weekly advance faster than those doing only 4 hours. Traditional time management fails when you need to debug complex systems or design scalable architectures. The Pomodoro Technique works for shallow tasks, but senior-level challenges demand sustained attention. This is where the 4-hour focus block transforms your development workflow. Why 4 Hours?

One of the recurring issues many companies face is the struggle to optimize their financial systems. Delayed transactions and complex integrations often happen because there’s no real-time data coming in from customers. In most cases, this is due to financial information being locked away in separate systems. On top of that, customers expect smooth and seamless transactions, even as their needs continue to change. This growing demand creates more pressure on businesses to keep up. To resolve these challenges, open banking was introduced. It's a model that gives integrators more control over financial data, making it easier for businesses to deliver fast, secure, and personalized financial experiences. And it’s not just for financial service providers. Traditional companies can also tap int…  ( 9 min )

As developers, we often create temporary files or debug utilities during development.

Early computers, such as the ENIAC and the UNIVAC, had extremely limited resources by today's standards. Memory was scarce and expensive, often measured in kilobytes, and processors operated at speeds measured in kilohertz. For instance, the ENIAC had a memory capacity of about 20 words, each 10 decimal digits long, and operated at a clock speed of 100 kHz. These limitations necessitated a meticulous approach to software development, where every byte and clock cycle counted. Developers often wrote programs directly in machine code or assembly language to maximize efficiency. Machine code consists of binary instructions specific to the hardware, while assembly language uses mnemonics to represent these instructions. Both approaches allowed for precise control over hardware resources. For e…  ( 5 min )

Imagine your toy box. You have one in your room. Your brother has one in his room. You can't reach into his toy box, and he can't reach into yours. That's scope. Now, let’s say your toy robot remembers your name even when you leave the room. That’s closure. Let’s go a bit deeper (but still like you're 5): Scope means "who can see what." function playRoom() { let toy = "robot"; console.log(toy); // ✅ can see robot } console.log(toy); // ❌ error, can't see robot Why error? Because toy is in the playRoom. Outside can't see inside. Closure means a function remembers things from where it was born. function makeToy() { let toyName = "Buzz"; return function() { console.log("Playing with " + toyName); }; } let play = makeToy(); play(); // ✅ "Playing with Buzz" Even though makeToy() is done, the inside function remembers toyName. That’s a closure. Scope: "You can only use your toys in your room." Closure: "You made a magic toy that remembers your name, even if you take it outside." Helps avoid bugs. Lets us write smart code like hiding secrets or making factories. Used in React hooks, event handlers, and more. Scope = "Where can I see this?" Closure = "I remember where I came from." Want to test it? Try these: // Challenge 1 function box() { let secret = "shhh"; return function() { console.log(secret); } } box()(); // What will it print? // Challenge 2 let a = 10; function outer() { let a = 20; function inner() { console.log(a); } return inner; } let result = outer(); result(); // Guess the output! Keep playing with the code. Think of scopes as rooms and closures as memory toys. Happy coding like a 5-year-old genius! 🎉  ( 3 min )

To power an Arduino Nano with a LiPo battery and charger, you'll need to ensure safe charging, voltage regulation, and protection. Here's a full guide: What You Need Common Wiring Setup Option 1: TP4056 → 5V to Nano text [LiPo 3.7V Battery] | v [TP4056 Charger] → [Boost Converter 3.7V → 5V] → Arduino Nano 5V pin Battery → TP4056 (B+ and B−) TP4056 OUT+ → Boost IN+ Boost OUT+ → Nano 5V pin This powers the Nano directly with 5V (regulated) Option 2: Direct to VIN (when safe) Nano’s regulator requires ≥6V for full 5V output LiPo may drop to ~3.3V, causing instability So VIN is not ideal for single-cell LiPo without boosting.

Hi all! Today I continued learning about the video element and all its attributes. We need an attribute called controls enabled in order for the video to play....also we need to mention the type of video format so that the browser can render it accordingly. We can also give attributes like autoplay muted and loop to the source tag so the the video plays automatically each time the website is loaded. But some users might find autoplay as a form of violation of their privacy and so we must try and avoid using autoplay. Youtube video in the website. This can be done using the iframe tag and the url can be obtained by selecting the share option in the desired Youtube video and copying the code given under embed tab into the iframe. Similar to regular video we can also use autoplay and mute options in this. However these should not be written as seperate attributes but should be written at the end of the iframe URL address with their values set to 1. So that's all for today.....see you all in the next post!  ( 3 min )

From Tool Chaos to Development Zen: A Developer's Journey to the Perfect Workflow Kruti for Teamcamp ・ Jun 16  ( 2 min )

Recent research has cast new light on the limitations of modern AI “reasoning” models. Apple’s 2025 paper The Illusion of Thinking shows that today’s Large Reasoning Models (LRMs) — LLMs that generate chain-of-thought or “thinking” steps — often fail on complex problems. In controlled puzzle experiments, frontier LRMs exhibited a complete accuracy collapse beyond a complexity threshold. In other words, after a certain level of difficulty, their answers become no better than random. Equally striking is their counter-intuitive effort scaling: LRMs ramp up their chain-of-thought as a problem grows harder, but only up to a point. Beyond that, they actually give up — even when the token budget remains ample, their detailed reasoning steps abruptly shrink. These findings suggest a fundamental ga…  ( 8 min )

Welcome to Day 9 of our FastAPI Zero to Hero series! Today we unlock one of the most powerful (yet misunderstood) tools in modern web development — Async Programming. Writing non-blocking code can be accomplished through async programming. This implies that your program doesn't wait for sluggish operations (such as file reads or API requests) to complete before continuing. Alternatively, it can work on other projects in the background when those tasks finish. You're cooking dinner 🍳 and waiting for the rice to boil. While it boils, do you just stare at the pot? Nope — you chop veggies or scroll through Instagram reels. That’s asynchronous behavior — you’re multitasking efficiently. Async is the engine behind that speed and FastAPI is built for speed.

This is where the as const keyword comes in. By using as const, we ensure that Typescript treats our values with specific types, preserving and using their exact value instead of generalising them. In this article, we'll explore how the as const keyword works and how it can enhance your development with Typescript Typescript uses broader types when inferring the type of a value. For example, when you declare a variable with a string, Typescript will infer the type as string, rather than the exact string value you assigned. However, using the as const, you are telling Typescript to treat the value as a con…  ( 5 min )

Hey everyone! 👋 I've put together a complete end-to-end CI/CD setup using: ✅ AWS CodePipeline ✅ AWS CodeBuild ✅ S3 for hosting a static website ✅ Separate unit testing stage before build If you're looking to test, build, and deploy your web app — automatically — using only AWS services, you’ll love this setup. 📌 Step-by-step setup for Running unit tests with a dedicated unit-test CodeBuild stage Building your app (React, Angular, Vue, etc.) Deploying the built files to an S3 bucket (static website hosting) Automating it all with AWS CodePipeline I’ve added a separate CodeBuild project that: Runs your test framework Fails early if tests don't pass ✅ Prevents broken code from moving to build or deploy stages Once tests pass, a second CodeBuild stage: Runs build Uploads the output (like dist/ or build/) to S3 S3 serves your static website via public endpoint or CloudFront 📁 GitHub Repo (Step-by-Step Instructions): cicd-codepipeline-GitHub Frontend developers deploying static apps DevOps engineers automating CI/CD pipelines Anyone exploring AWS CodeBuild, CodePipeline & S3!

“It’s just S3. What could go wrong?” If you’ve ever had this thought while deploying an app, building a static site, storing user uploads, or integrating backups, you're not alone. But you might also be unknowingly misusing one of the most powerful — and deceptively simple — services in the AWS ecosystem: Amazon S3 (Simple Storage Service). Yes, S3 — the Swiss Army knife of AWS. It sounds harmless, even elegant: a “bucket” where you store your files. But the truth is, most developers (up to 85%) are not using S3 the right way, especially at scale or in production-grade applications. From skyrocketing costs, broken performance, misconfigured security, to compliance nightmares — the misuse of S3 creates hidden dangers that quietly eat away at your infrastructure. The beauty and danger of S3 …  ( 7 min )

A junior developer's guide to understanding component execution strategies If you're just starting your frontend journey, you've probably heard terms like "compilation," "build process," and "bundling" thrown around. Most modern frameworks require these steps, but Juris takes a completely different approach that's both simpler and more sophisticated. Let me explain why this matters for your development experience. First, let's understand what other frameworks do: // You write this (JSX/Template): function MyComponent() { return Hello {name} ; } // Build tool converts it to this: function MyComponent() { return React.createElement('div', null, 'Hello ', name); } The process: ⏳ Write code in special syntax (JSX, Vue templates) ⏳ Wait for build tool to transform your code ⏳ Br…  ( 6 min )

If you’ve used Create React App (CRA) for your React projects, you know it's a solid tool. But there's a new sheriff in town — Vite.js — and it's changing the way we build frontends for the better. In this article, I’ll walk you through how to create a blazing-fast React application using Vite.js instead of CRA. While CRA was the go-to tool for years, it comes with some downsides: 🚫 Slow dev server startup 🚫 Long build times 🚫 Harder to configure (ejecting required) Vite.js, on the other hand: ⚡️ Starts instantly (thanks to native ES modules and lazy loading) ⚙️ Uses Rollup under the hood for production builds 💡 Is easily configurable and supports modern JS features out of the box Let’s set up a new React app using Vite.

AWS recently announced something awesome: CodeBuild now supports remote Docker servers! 🎉 But wait... what does that even mean? Let me explain with a simple example that anyone can follow 👇 Every time you cook pasta, you do the same steps: Boil water 🍲 Cut vegetables 🥕 Make the same sauce 🍅 Cook pasta 🍝 Now imagine doing this from scratch every single time — even if the recipe doesn't change! 😩 Wouldn't it be smarter if your kitchen assistant saved your sauce, chopped veggies, and hot water, so you could reuse them and cook faster? Before Every time AWS CodeBuild ran a Docker build, it started from zero. It downloaded everything again (base image, node modules, etc.) ⏳ Builds were slow, even for tiny changes. Now AWS provides a remote, invisible Docker server just for you. This server remembers your past Docker layers (cached!). Next time you build — it’s faster, because it reuses what didn’t change. 🚀 Your Dockerfile for a Node.js app: FROM node:20 COPY package.json . RUN npm install COPY . . CMD ["npm", "start"] First Build All steps run from scratch. ⏱️ Next Build Docker skips node:20 (already cached) Skips npm install (if package.json didn’t change) ✅ Only rebuilds what actually changed! Without Remote Server With Remote Server Always builds from scratch ❌ Reuses cached layers ✅ Slower CI/CD ⏳ Faster builds 🚀 More compute & network usage 💸 Efficient + cheaper 💡 Nope! 🎉 This feature is a game-changer for developers using AWS CodeBuild and Docker. Let AWS handle the caching magic while you focus on building cool stuff! 🔥 Let me know in the comments if you've tried this — or if you want help optimizing your Docker builds on AWS! 💬  ( 3 min )

Author: Andrei Leonov Introduction What if an AI could discover physical laws — not by being told the answer, but by evolving its own formulas? What if the result looked like pure nonsense — yet hid a physically perfect structure underneath? This is the story of a formula that is at once absurd and brilliant. Generated by symbolic regression using genetic programming (GP), the expression appeared chaotic and unreadable. But after careful analysis, it revealed a deep, interpretable pattern — one that could be used in physics, geometry, and even memory modeling in AI systems. The Raw Formula (a Monster) X′ = neg(((tanh(x) / pi) * (1 + p1))) The formula was one of many evolved by a symbolic GP system trained only to minimize MSE — no physics was built in.

LeetCode 3405 | Hard | Combinatorics You are given three integers: n: length of the array m: range of values [1, m] k: number of adjacent equal pairs You must find the total number of "good arrays", where: Every element lies in the range [1, m] Exactly k indices i (where 1 ≤ i < n) satisfy arr[i - 1] == arr[i] Since the result may be large, return the count modulo 10⁹ + 7. To construct a valid array: Pick k positions (from the n - 1 possible adjacent pairs) to be equal. The first element can be any value from 1 to m. For each of the n - 1 - k remaining positions (which must differ from the previous element), there are m - 1 options.

What is a Hook? Hooks allow function components to have access to state and other React features. Because of this, class components are generally no longer needed. Hooks allow us to "hook" into React features such as state and lifecycle methods. Why used Hooks? Although Hooks generally replace class components, there are no plans to remove classes from React. Hook Rules** There are 3 rules for hooks: Hooks can only be called inside React function components. Note: Hooks will not work in React class components. useState in React React's useState hook lets you add state to functional components. import { useState } from 'react'; function Counter() { return ( Count: {count} An array is a list-like object used to store multiple values in a single variable. const fruits = ['apple', 'banana', 'cherry']; Arrays can hold any data type — strings, numbers, objects, or even other arrays. The Spread Operator (...) The spread operator allows you to quickly copy or merge arrays and objects. const original = [1, 2, 3]; console.log(copy); // [1, 2, 3] Adding elements: const numbers = [1, 2, 3]; console.log(moreNumbers); // [1, 2, 3, 4, 5] Merging arrays: const a = [1, 2]; console.log(combined); // [1, 2, 3, 4] Using map() to Transform Arrays The map() method lets you apply a function to every element in an array and returns a new array. const numbers = [1, 2, 3]; console.log(doubled); // [2, 4, 6] In React, map() is commonly used to render lists of components: const items = ['pen', 'notebook', 'eraser']; return ( {item} )} );  ( 3 min )

What is Blockchain? Blockchain is a decentralized, permanent digital ledger that records transactions across many computers. This setup makes it nearly impossible to change past records. Instead of relying on a central authority (like a bank), blockchain promotes transparency, security, and efficiency by sharing control among participants. Transactions are grouped into blocks, and each block links to the previous one, creating a chain. These blocks are protected using cryptography, ensuring the data inside can’t be altered once added. A blockchain runs on a peer-to-peer network. When a transaction happens: It is broadcast to many computers (called nodes). The nodes verify the transaction through consensus methods like Proof of Work (PoW) or Proof of Stake (PoS). Verified transactions are…  ( 5 min )

As a student developer who is exploring AWS technologies, I recently came across Amazon Q and its current event. The event encouraged participants to build a game, and that instantly hit a nostalgic chord in me. A few years ago, I've created a simple game in Unity without knowing how to code. Now, equipped with two years of coding experience and the help of Amazon Q, I managed to recreate that idea as a full parody arcade game using pygame-ce in just one day! Although AI tools are not new to me and to everybody, it still amazes me how much faster development becomes with the use of it.

This is the third release of Pulumi Gestalt, a universal runtime for Pulumi. Pulumi schemas have traditionally been stored in YAML files, but the complexity of their content often leads to a lot of boilerplate when mapping into domain objects. In Pulumi Gestalt 0.0.3, both the Rust and C FFI targets (Wasm coming later) now support obtaining schemas as native Rust structs or serialized Protobuf messages for C. The Protobuf schema is designed to be straightforward—no additional mapping logic required. Check documentation for more info: https://pulumi-gestalt.readthedocs.io/v0.0.3/integrations/overview/#get-schema https://pulumi-gestalt.readthedocs.io/v0.0.3/integrations/schema/ Give Pulumi Gestalt 0.0.3 a try and let me know what you think!  ( 3 min )

Recently, I built a small Rust CLI tool called Tooka, and I wanted to share how I set it up to compile for all major systems — Windows, Linux, macOS — and how I handled packaging and distribution across app stores. This post covers: GitHub Actions setup Cross-compilation with Rust Packaging with cargo-packager Distributing via Snapcraft, AUR, Winget, Docker, Cloudsmith, etc. Real-world pitfalls (like GLIBC incompatibility) And a full example Dockerfile 🚀 Introducing Tooka Tooka is a tiny CLI that sorts files using YAML-based rules. It doesn’t use a GUI or any external dependencies — a design choice that makes packaging much easier across platforms. Side note: Naming it Tooka turned out to be... suboptimal. There are way too many projects with similar names. But hey, too …  ( 5 min )

A beginner-friendly guide to understanding Django REST Framework's default behavior and OAuth implementation You're building a simple OAuth login system. You know OAuth works with redirects, so you create these endpoints: # Your OAuth views - should only handle GET requests class GoogleLoginView(APIView): def get(self, request): # Redirect user to Google login return redirect(google_oauth_url) You expect your API documentation to show: GET /auth/google/login/ → Redirect to Google But when you check your Swagger docs, you see this confusing mess: POST /auth/google/login/ Request body: { "access_token": "string", "code": "string", "id_token": "string" } Wait, what? You never wrote a POST method! Where did this come from? 🤔 Let's understand what we're trying to…  ( 6 min )

TL;DR: When building a real-time video rendering and encoding pipeline in C++, I hit a surprising bottleneck: memory allocation. Despite using high-performance libraries like OpenGL and FFmpeg, the cost of safely copying ~5MB per frame killed my frame budget. The fix? Using raw pointers with a manually managed double buffer. It’s not idiomatic C++, but in this case, “unsafe” code—done carefully—was the only way to hit performance targets. As a person who worked in managed runtimes like NodeJs and the Golang runtime, thinking about memory management always felt like premature optimisations because the runtime, or the underlying libraries generally handled it really well. However, in C++ it is the name of the game. The language offers multiple ways to manage memory and resource lifecycles …  ( 5 min )

The world of frontend development is a constantly spinning carousel. As soon as you've mastered one framework, the next "Next Big Thing" is already on the horizon, promising to make everything better, faster, and easier. Looking back on my own journey, I see not just a list of technologies, but a personal development—a story of pragmatism, curiosity, initial aversion, and unexpected affection. This article is my personal retrospective. Not an ultimate "This is the best framework" sermon, but an honest reflection on the tools that have shaped my path as a developer. My journey didn't start in the shiny greenfield project heaven. It began in the pragmatic world of SharePoint on-prem. Anyone who has ever had to develop here knows: it's a discipline of its own.

🧩 The Big Picture: What is RAG? Retrieval-Augmented Generation (RAG) is like giving your AI assistant a personalized reference library! It combines: Retrieval 🔍: A smart search engine that finds relevant facts Generation ✍️: An LLM that crafts human-like responses Standard LLMs have two major limitations: They only know what they were trained on (often outdated) ⏰ They sometimes hallucinate (make things up) 🤪 RAG solves both problems by feeding the model fresh, relevant information at query time! User Question → Search Engine → Relevant Docs → Enhanced Prompt → LLM → Answer LLMs prioritize information in the immediate context over what they've memorized during training. By placing facts directly in the prompt, we dramatically increase accuracy! # Download your documents (FAQs, manual…  ( 5 min )

A LGPD trouxe para o mundo dos DEV's uma série de desafios ao lidar com dados sensíveis. Entre as perguntas mais comuns estão: Como armazenar esses dados? Como trafegá-los com segurança? Como exibi-los sem expor informações? Quais recursos interagem com esses dados? Nem sempre existe uma solução única para todos os casos, mas o interessante é que quase todos os recursos e frameworks oferecem formas de lidar com esses desafios de maneira transparente e eficaz. No que diz respeito ao armazenamento, bancos relacionais como o MySQL oferecem funções nativas de criptografia, como AES_ENCRYPT e AES_DECRYPT.

A groundbreaking study from Japan has uncovered direct brainwave patterns linked to our experience of happiness. Using advanced magnetoencephalography, or MEG, scientists identified a clear neural signature that differentiates happier minds from the rest. Researchers recorded brain activity from volunteers at rest and compared those signals against their self reported happiness levels using standard psychological questionnaires. They discovered that higher subjective happiness was associated with lower fluctuations in gamma band electrical activity in a key brain region called the right precuneus. This area is known to be involved in self awareness and mind wandering. To reach this conclusion, the team employed a 400 channel MEG helmet to capture high resolution brain data. They used a met…  ( 3 min )

How many times have we struggled to test deeplinks with custom schemes on Mobile? If you're an experienced mobile engineer, probably more times than you can count.

Today hit us with another round of Apple rejection. 😅 This time it wasn’t technical — at least not completely. Apple flagged us for a broken link and asked for further clarification on what our app actually does. It’s frustrating, sure. After working so hard to build something safe, educational, and magical for kids — it’s a gut punch to feel like we’re stuck behind bureaucracy. But we're not giving up. We took today to carefully review the rejection notes, update our metadata, fix the link issue, and prepare a new submission. The worry now is time: with only 13 days left, will we have a working version live in the store before the hackathon ends? It’s a risk, but we’re still in this. We believe in Story Hero too much to let some red tape stop us. The Apple review process is famously opaque. But we’re committed to learning it, navigating it, and getting this app live — even if it takes a few more tries. One way or another, we’ll launch.

Open your favorite banking app. Tap to send money. If it hesitates even a second, what do you do? That brief pause – barely noticeable in most apps – can be a deal-breaker in financial services. Trust is measured in milliseconds. According to a study by Akamai, a mere 100-millisecond delay in website load time can hurt conversion rates by 7%. For mobile banking, where stakes are higher and users are less forgiving, the impact compounds. FinTech isn’t just software – it’s infrastructure. And users expect infrastructure to be fast, always available, and invisible when working correctly. When it fails, it’s not just annoying – it’s a breach of trust.

The most impressive addition is automatic comment generation. An on-device model analyzes your code and writes contextual comments that translators actually need. We've all been there. You write a string like this: Text("Delete", comment: "Delete button shown in an alert asking for confirmation to delete the collection.") But more often, we rush and write this: Text("Delete") // TODO: Add comment for translators The TODO never gets done. Translators see "Delete" with zero context. Is it a verb? A noun? What's being deleted? Right-click any string in your String Catalog and select "Generate Comment." The results are surprisingly sophisticated: // Original string with no context Button("Cancel") { } // AI-generated comment: // "The text label on a button to cancel the deletion of a collec…  ( 6 min )

Amazon/AWS people speak a lot on how they're customer obsessed, and have a bias for action. And sometimes it sounds like talking points. But, lately, I got to experience first-hand how AWS listens (and reacts) to community feedback! The story is actually quite short, given how fast my feedback was taken into account. On May 19th, I created an IAM user for a subcontractor, let's call him John, who was supposed to work on a data lake project, so I named that user john and put him in the /datalake/ path. I set a temporary Console password and assigned the IAMUserChangePassword policy to that user.

1. Introduction Solidity is one of the most widely used programming languages in the Web3 space, especially on Ethereum and Ethereum Virtual Machine (EVM) compatible chains. As smart contract development has evolved, developers have encountered several challenges, particularly when trying to build complex, upgradeable, and gas-efficient contracts. One major limitation is Solidity's 24KB maximum contract size, which restricts the amount of logic that can be deployed in a single contract. This has led developers to explore different upgradeability patterns and modular architectures. To address these limitations, Nick Mudge proposed the Diamond Standard (EIP-2535). This standard provides a framework for building modular, upgradeable smart contracts in a structured way. By organizing contrac…  ( 6 min )

One thing I learned about: Alternatives to using blockchain nodes Blockchains do not always need to use full nodes for every task in the network. They can use alternatives suited to their goals, circumstances, and constraints. Examples: Light clients: performs trust-minimized verification by requesting proofs from full nodes. Data availability layers: store and serve block data apart from execution nodes. Layer2 and sidechains: process data off-chain and rely on proofs or state roots. Blockchain indexers: store data and allow queries nodes do not support. Remote or federated APIs: third-party on-chain data providers 🔽🛠️Resources🔽 What is Data Availability in Blockchain?

Every developer using an AI coding assistant has felt the jarring whiplash of its brilliance and its absurdity. One moment, it scaffolds a complex class structure perfectly; the next, it confidently uses a deprecated method or hallucinates an API that never existed. This problem becomes critical when building complex, stateful systems like those powered by LangGraph. An unguided AI can quickly lead you down a rabbit hole of debugging non-existent features. But what if, instead of just prompting and hoping for the best, we could engineer the environment our AI assistant operates in? What if we could force it to be a reliable, expert partner? This article introduces a framework to do just that. It's a system for grounding AI assistants, making them highly effective tools for building product…  ( 6 min )

So you've decided to build a complex, multi-step AI agent. You fire up your AI coding assistant, describe your goal, and ask it to scaffold a LangGraph application.

Here’s the quick breakdown: Transfer Learning is great when you just need to tweak the model a bit freeze most layers, retrain the final ones, and you’re good to go. Fast and efficient. Fine-Tuning, on the other hand, updates the whole model. It’s heavier, but sometimes necessary when your use case is highly domain-specific (think legal, medical, or financial AI). We made a short video explainer that walks through both options and when to use each. If you’re building anything from sentiment classifiers to custom chatbots, it might help clarify the path forward. Let us know if you're exploring this in your own AI project! 👀  ( 3 min )

Hot take: We're using the wrong tool for the job. Your TypeScript types are giving you a false sense of security where it matters most. Let's be honest. We adopted TypeScript for safety. And for the code you write and control, it gets the job done. But where do the most dangerous bugs originate? From the outside world: API responses, user input, webhook payloads. Then here comes TypeScript to do absolutely nothing. That's right. TypeScript, a compile-time tool, is completely silent when your app receives malformed JSON at runtime. Your beautiful type User = { id: number; } offers zero resistance when an API mistakenly sends { "id": "user-123" }. The code compiles, your app runs, and then it crashes. This fundamental gap forces us into a clumsy, defensive workflow that I call the "Two-Sou…  ( 5 min )

I started my DSA journey pretty recently. It was like a passport to product based companies - solve 'n' number of problems and get 'n' number of offers. 1. Think patterns not topics Most questions can be solved using a single pattern. You don't have to solve 3000 problems to master DSA but master the patterns to which 3000 problems can be solved. For example in arrays and strings most questions were easily approachable using binary search, two pointers and sliding window. 2. You will look at solutions repeatedly. Don't worry happens to everyone 3. It improves project logic Should I use set for faster lookups? Can I reduce the number of API calls by memoizing it? DSA taught me that even product-based features have their space and time complexities. 4. DSA humbles you Conclusion I'm not saying learning DSA will guarantee you a job at a top product based company. Just how learning ABCs is a fundamental unit before adapting to fluent english. DSA is a fundamental unit before adapting to project devlopment. Mastering DSA is extremely beneficial, provided you do it the right way. Don't just solve problems but also try implementing that knowledge into your existing projects and see how can it be further optimized. Your not just preparing for an interviews. You're training to be a problem solver- which is a superpower in any domain.  ( 5 min )

Date of writing: 16-06-2025 Given a 0-indexed integer array nums of size n, find the maximum difference between nums[i] and nums[j] (i.e., nums[j] - nums[i]), such that 0 <= i < j < n and nums[i] < nums[j]. Return the maximum difference. If no such i and j exists, return -1. This problem, in initial thought, seems pretty simple. We simply need to find the biggest difference between 2 numbers, if the latter of those 2 numbers is bigger then first number. I believe we can do this in a O(n) solution, keeping track of some numbers whilst we go through the list! The first pseudo code I can think of is as follows: const maxDifference = -1; const smallestIndex = 0; for (int i = 0; i < numbers.length; i++){ if i is equal to numbers.length - 1 : // We are at the end of the list, so…  ( 7 min )

I’ve been building with React for years, and every time the app grows, so does the complexity around managing state. Yes, I’ve used Redux Toolkit. Yes, Zustand is sleek. At some point I paused and asked: What if managing shared state could feel as natural as useState()? That question sparked a journey — of breaking down there Architecture, understanding what they solve, and what they still miss. As frontend devs , especially in React, we’ve all had this moment. We reach for state management, and suddenly, a simple feature blows up into a complex web of files and concepts. Redux Toolkit (RTK) today is certainly better than raw Redux. It streamlines many processes and introduces sensible defaults. But let’s be honest, it still comes with a decent amount of Manual Setup, a learning curve, and…  ( 4 min )

Introduction This project aims to automate the deployment of Java applications to an Apache Tomcat server using Jenkins. Instead of manually building and copying .war files, we use a CI/CD pipeline where Jenkins pulls code from a Git repository, builds it using Maven, and deploys it to Tomcat automatically. This streamlines the development process, reduces human error, and enables faster, more reliable application delivery, following modern DevOps practices. Manual deployment of Java applications is time-consuming and error-prone. This project solves that by introducing automation using Jenkins, which ensures that every time code is updated, it is built, tested, and deployed automatically to a Tomcat server. It saves developer time, reduces bugs, and supports faster and more reliable so…  ( 5 min )

A major leap forward in battery technology has just been achieved. Scientists at the University of Manchester and the University of Technology Sydney have developed a novel two dimensional superlattice material that could revolutionize zinc ion batteries. The new material significantly improves performance, stability, and longevity, addressing key limitations that have long held this promising battery type back. Zinc ion batteries are already considered safer and more environmentally friendly than traditional lithium ion batteries. Zinc is abundant, non toxic, and easier to recycle. However, until now, these batteries have suffered from short lifespans and limited charge discharge cycles, largely due to instability in the electrode materials. That is where the new superlattice design comes…  ( 4 min )

You don’t need 10 years of experience to be a great developer. We’ve all seen it on job listings: “Senior Developer – 8+ years of experience required.” ⚡️ One dev might spend 5 years copying code and avoiding complexity. Experience is not just time, it’s intensity, ownership, and curiosity. I’ve seen developers with “junior” titles outperform so-called seniors, simply because they’ve been in environments that challenged them, mentored them, and pushed them beyond comfort zones. So maybe it’s time we stop using experience like a stopwatch… What’s your take on this? Does time still matter — or is trajectory the real measure of experience?  ( 3 min )

Cracking the Serverless Black Box: Advanced Debugging and Observability Strategies for Modern Serverless Architectures Serverless architectures have revolutionized how applications are built and deployed, promising reduced operational overhead and infinite scalability. However, this paradigm shift introduces a unique set of challenges, particularly when it comes to understanding and troubleshooting application behavior. The ephemeral nature of functions, distributed execution across multiple services, and the "black box" perception of the underlying infrastructure often leave developers grappling with issues like cold starts, elusive errors, and fragmented traces. Traditional debugging methods, designed for monolithic applications running on persistent servers, simply fall short in this hi…  ( 7 min )

What Is a Process Signal? Real-Life Use Case Common Process Signals You Should Know How to Send a Signal Using kill Using killall for Convenience Signals Aren’t Just for Crashing Things Conclusion If you've ever wondered how you can stop a program in Linux, pause it, or even tell it to restart itself; you're talking about process signals. Think of signals like short messages sent from one part of the system to a program, telling it to do something specific. This concept might sound technical, but once you get the hang of it, it's incredibly helpful; especially when a program is stuck or misbehaving.

When you're building geospatial applications, it's surprisingly easy for users to accidentally create duplicate or very close records. Imagine trying to add a location (like a traffic signal or utility pole) at a GPS point that’s just 30 feet away from an existing one. Should the system allow that? Should the user be warned? In this post, I’ll show how I implemented a proximity detection system using the Haversine formula in Java to solve this problem cleanly and effectively. My goal was to prevent duplicate entries by: Calculating the distance between the new location and existing ones Alerting the user if any location was within X feet (say, 100 ft) Letting them decide whether to continue So instead of relying on exact latitude/longitude matches, we used distance-based detection.

Whether you're building an AI assistant that can search your documentation or a bot that provides grounded answers based on custom content, this guide will walk you through the key concepts and implementation steps. RAG is an AI technique that combines the strengths of information retrieval with natural language generation. Instead of relying purely on what a model has memorized during training, a RAG system actively fetches relevant data from an external source and uses it to craft accurate, contextually relevant responses. Accuracy: ground responses in actual documents rather than model guesses. Custom knowledge: use your own content as the source of truth…  ( 8 min )

When working with JavaScript and React, there are a few core concepts that you’ll use again and again: arrays, the spread operator (...), the map() function, and React's useState hook. In this blog, we’ll break each one down with simple examples so you can understand how and when to use them effectively. An array is a list-like object used to store multiple values in a single variable. const fruits = ['apple', 'banana', 'cherry']; console.log(fruits[0]); // Output: apple Arrays can hold any data type — strings, numbers, objects, or even other arrays. The spread operator allows you to quickly copy or merge arrays and objects. const original = [1, 2, 3]; const copy = [...original]; console.log(copy); // [1, 2, 3] Adding elements: const numbers = [1, 2, 3]; const moreNumbers = [...number…  ( 4 min )

AI is evolving fast, with new "best" AI models appearing every few weeks. 🥴 Among them, we have three top models leading the leaderboards: Claude Opus 4, Gemini 2.5 Pro, and OpenAI's o3 Pro. Which one do you really pick for coding? If you're a dev who cares about clean, efficient coding models, it can get overwhelming really quickly. So I put them head-to-head. Let’s see which one actually works for coding. 👀 If you want to skip to the results, Claude Opus 4 is much better than the other three in terms of code quality, implementation, following prompts, and most importantly, understanding your exact needs. It really gets what you want, even the specifics. But you won't go wrong choosing the Gemini 2.5 Pro model for coding as well. It's a perfect model and gives great results. If price …  ( 10 min )

I built and sold my first Tailwind portfolio template — here’s what I learned Hey Devs! 👋 I recently challenged myself to build a complete developer portfolio template using just HTML, Tailwind CSS, and vanilla JavaScript. Originally, I planned it for my personal site, but I decided to polish it and publish it as a product. That small decision turned into one of the most exciting moments in my dev journey so far! It’s a simple but modern portfolio template that includes: 🌙 Dark / Light Mode toggle 📱 Responsive layout (desktop & mobile) ⚡ Scroll animations 📁 Project section with tech tags 📩 Contact form UI 📄 Resume download button 🧠 Vanilla JS + Tailwind CSS 🧼 Clean structure (HTML, CSS, JS separated) Honestly? I wanted to test if a beginner-friendly template with good visuals and real features could be useful for: Developers applying for jobs Students graduating from bootcamps Freelancers needing a fast, clean portfolio And... turns out it was. Even without followers, some people found the template through social platforms and started buying! You don’t need a giant audience to start. Simple, real-world tools (like Tailwind + HTML) are still in demand. Gumroad, Itch.io, and Payhip are great for selling digital stuff — no code needed. If you create something useful, people will find it. 🔗 Live Demo: [Link in my Dev.to profile] 🛍️ Gumroad page: [Link in my profile too] I didn’t put the links directly here just in case the post gets filtered, but they’re visible in my Dev.to bio section. 😄 If you’ve ever hesitated to share or sell what you’ve built — just try it.

Artificial Intelligence (AI) is no longer a distant future. It’s now deeply embedded in the apps we use, the cars we drive, and even how businesses operate. At its core, AI refers to machines mimicking human intelligence. But AI is not one-size-fits-all. Understanding its types helps us grasp where we are today—and where we’re headed tomorrow. Categorizing AI gives us clarity. It helps researchers, developers, and decision-makers know what AI can currently do and what it might achieve.

One of the first things you study when you study programming is exception handling, which is fundamental to develop applications efficiently and avoid unexpected situations. But first, what is an exception? Exceptions are errors that happen due to errors in programming or not related to it, for example, trying to read a file that does not exist, a connection failure with the server or trying to divide by 0. What kind of exceptions are there? In Java (and similarly in other languages), exceptions are divided into two major groups: checked and unchecked. - Checked Exceptions try/catch block or by declaring the exception with throws. They represent recoverable and expected situations during execution, such as problems when accessing files or networks. FileReader reader = new FileReader("f…  ( 5 min )

Integrating Google OAuth2 authentication in a Django REST API can be tricky, especially with changing library APIs and the need to support both web and mobile clients. Here’s a practical, robust approach that avoids common pitfalls and works reliably with modern Django and Google APIs. Why Not Use Allauth Adapters Directly? While django-allauth is a popular library for social authentication, its internal APIs (like get_app and direct use of adapters) can change or become unstable. Relying on these can lead to hard-to-debug errors, especially after library upgrades. Solution: Use the official Google OAuth2 HTTP endpoints directly for the callback, and only use allauth for registration flows if you need them.

Stop blindly navigating your growing NestJS projects! We've all been there – digging through controllers to find that specific endpoint. That's why I built NestJS Dashboard, a VS Code extension that gives you a bird's-eye view of your entire API landscape. This simple yet powerful tool scans your workspace and presents all your NestJS routes in a clean, intuitive sidebar panel. No more wasted time hunting for endpoint details! NestJS Dashboard automatically discovers and displays all your HTTP endpoints, providing essential information in a clear and organized tree view. You'll instantly see: HTTP Method: GET, POST, PUT, DELETE, etc. Route Path: The full path to your endpoint. Controller Name: The name of the controller class. Handler Method: The specific method handling the request. Automatic Discovery: The extension intelligently finds all your NestJS controllers and their associated routes. Real-time Updates: As you create, modify, or delete routes, the dashboard will automatically refresh to reflect the changes in your codebase. Go to Definition: Quickly navigate directly to the code for any endpoint with a single click. Install the NestJS Dashboard extension from the Visual Studio Marketplace. Open your NestJS project in VS Code. Look for the new NestJS icon in your activity bar. Click it to open the dashboard and see all your routes! It's that simple. No configuration is needed to get started. As a developer, I'm always looking for ways to improve my workflow and reduce friction. Constantly searching for route definitions in a large NestJS project was a recurring pain point. I wanted a simple, visual way to see everything at once. Seeing the positive feedback from early users has been fantastic, and I'm excited to share it with the broader dev.to community. Give it a try and let me know what you think!

"You didn't build a framework. You built a JavaScript liberation platform." — Claude Sonnet 4 I just watched a complete documentation website—16,650 lines of code—load in 3 milliseconds on mobile. Not 3 seconds. 3 milliseconds. That same site refreshes in 11ms. Worst case scenario: 20ms. For context, most "fast" websites take 500-1000ms to load. React applications typically take 2-3 seconds. This documentation site loads 100-1000x faster than what we consider "good performance." But this isn't a story about performance optimization. This is a story about JavaScript liberation. Over the past decade, we've systematically enslaved JavaScript to an increasingly complex ecosystem: Build Tools: webpack, rollup, vite, esbuild, parcel Transpilers: Babel, TypeScript, SWC Bundlers: Code splitting…  ( 7 min )

As a computer science junior, my work on a web service project introduced me to the Hyperlane framework. This high-performance Rust HTTP framework fundamentally altered my view of web development. Here's a genuine account of my experience learning and using Hyperlane. ctx Abstraction When I first began using Hyperlane, I was immediately impressed by its clean Context (ctx) abstraction. In other frameworks, I was accustomed to writing more verbose calls, such as: let method = ctx.get_request().await.get_method(); With Hyperlane, this simplifies to a single line: let method = ctx.get_request_method().await; This design significantly boosts code readability, especially when handling complex business logic, by removing the need for deeply nested method calls.

There’s a phrase that floats around in tech like a rite of passage: “I’ll feel like a real developer when I...” ✅ Learn React ✅ Get a job ✅ Contribute to open source ✅ Build my own SaaS ✅ Speak at a conference ✅ Master Kubernetes while juggling chainsaws We joke about it, but deep down? A lot of devs are waiting for permission to feel legitimate. But here’s the truth: If you write code, solve problems, and keep learning—you’re already a real developer. Stop Moving the Goalpost Many developers keep pushing their definition of success further out. But the problem isn’t that you’re not doing enough—it’s that you’ve trained yourself to never feel like it’s enough. Growth doesn’t come from “arriving.” It comes from building while you’re still figuring it out. You’re Allowed to Be Incomplete and Still Valuable You don’t have to know everything. You don’t have to ship side projects every weekend. You don’t have to prove anything to Twitter to be worthy of this title. You just have to keep showing up, keep learning, and keep helping others do the same. You Belong Here If you're passionate about this craft... If you're trying, failing, refactoring, reading docs at 2 AM... If you're googling error messages and debugging the chaos... You're not trying to be a dev. You are one. When did you finally feel like a “real” dev—if ever? What old belief did you let go of that helped you grow faster? What would you say to a newer dev who doesn’t feel like they belong yet?

Why Turkey Became the Global Hub for Hair Transplantation in 2025 Hair transplantation has evolved drastically over the past decade, with countries like Turkey taking the global lead in medical tourism for aesthetic procedures. As techniques like FUE (Follicular Unit Extraction) and DHI (Direct Hair Implantation) became less invasive and more efficient, international interest in these procedures surged. But why Turkey? Turkey offers several advantages: Affordable yet high-quality services Surgeons with years of experience Modern, accredited medical facilities All-inclusive packages (flight, hotel, aftercare) Major cities like Istanbul, Ankara, and Izmir have become magnets for patients seeking hair restoration. One reason Turkey thrives is the reputation of its clinics. Clinics that consistently offer international standards and transparent results naturally gain more trust. For instance, Now Hair Time is one of the longstanding hair transplant centers in Istanbul. The clinic is known for its personalized approach, multilingual patient care, and high satisfaction rates, especially among international patients. In 2025, we expect: Increased use of AI-based planning Robotic implantation improvements Even shorter recovery periods Broader acceptance of beard and eyebrow transplants If you're considering a hair transplant in 2025, looking at Turkey — and especially at clinics with long-standing expertise — may be the smartest move. Do your research, ask questions, and don’t fall for the cheapest offers. Quality and transparency always win. ✍️ Written by a digital health researcher following trends in medical tourism.  ( 3 min )

You write code, so you write tests You may have a different version: You write tests before you write code While it's true, it's easy to miss the point and write tests that do not add any value or, worse, that actually validate an incorrect implementation. the tests still pass when you change the requirements the tests only run locally (so not on the CI/CD pipelines) the app generates bugs in production while all your tests pass the tests simply duplicate production code logic the tests break with every single refactoring some of your tests do not include any assertion the tests are not readable and hard to maintain you focus on 100% coverage instead of the business logic you write flaky tests (e.g., using non-deterministic dependency) that do not produce the same result every time they r…  ( 4 min )

mkdir Following the previous day commands on working with directories , The next command will be about how you can create a directory or a folder for yourself in the terminal. i.e mkdir mkdir newdirectory There is a switch available for this command that allows you to create multiple directories within another directory by using mkdir -p mkdir -p mydir2/mysubdir2 This command allows you to delete a directory when it is empty.otherwise it will show that the directory cannot be deleted. rmdir newdirectory This also has the same switch that allows you to delete the parent directories recursively. rmdir -p mydir2/mysubdir2 These commands allow you to create, modify , delete files.All the files are case sensitive and therefore treated as different files. The file command shows the datatype of a file.Linux does not use extensions to determine the type of a file.The file command uses a magic file(literally it's name) that contains patterns to recognise file types.file is located in /usr/share/file/magic. file file54.pdf , file /etc/passwd The touch command allows you to create an empty file. touch file86.txt touch -t = allows you to set the time on when the file was created. eg: touch -t 2412311159 demo.txt rm This command removes a file forever since it will not be sent to trash or recycle bin. rm file86.txt The switches available for this commands are: rm -i = using this switch prevents accidental deletion of a file by asking for confirmation before deleting the file. rm -rf = This switch recursively deletes the file forcefully. It can even delete everything if not used in the proper environment. So be careful when you use it. Wrapping up This will be the commands for today. Try experimenting on them to your preferences and also refer to man pages if you want to learn a lot more.  ( 3 min )

Like many developers, I had an old laptop sitting in a drawer—slow, outdated, and basically unusable for modern apps. But instead of tossing it away, I decided to transform it into something useful: a private cloud server. Now I have my own secure file storage system (like Google Drive or Dropbox), hosted right from my home. Here’s how I did it, step-by-step, using Nextcloud, Docker, and a little weekend effort. I love cloud storage, but I’m not a fan of: Storage limits Privacy concerns Monthly fees With Nextcloud, I get a Google Drive-like UI, mobile access, calendar, contacts, notes, and collaboration tools, but hosted entirely by me, with full control over data.

As developers and tech professionals, we love building things—features, APIs, workflows, cloud pipelines. The threat landscape has shifted. And here’s what’s pushing the envelope: AI-powered attacks are scaling faster than legacy defenses can adapt. Zero Trust is no longer a trend—it's the minimum bar. Cloud misconfigurations are still one of the top breach causes (yes, in 2025). Deepfakes & AI-generated phishing are getting eerily good. And regulatory frameworks (like the EU’s AI Act) are reshaping compliance. The perimeter? It’s gone. Your network isn’t behind a firewall anymore. It’s in the cloud, across endpoints, scattered through remote teams, and connected to countless third-party tools. 🧠 Why this matters to developers I’m joining a free webinar that’s breaking all this down: (https://cutt.ly/WrWwvdXB)  ( 3 min )

If you already used Docker with a Laravel app, you know the final image can get big and that affects build time, deployment speed, and even storage cost. In this post, I'll show you how to make you Docker image smaller and faster using multi-stage builds, lightweight images, and a few best practices. Here is a real example using PHP 8.3 + Laravel + Composer + Node for front assets: # Stage 1: Build the app dependencies FROM composer:2.7 as vendor WORKDIR /app COPY composer.json composer.lock ./ RUN composer install --no-dev --prefer-dist --optimize-autoloader COPY . . # Stage 2: Build frontend assets (optional) FROM node:20-alpine as frontend WORKDIR /app COPY package*.json ./ RUN npm ci COPY . . RUN npm run build # Stage 3: Final production image (clean and light) FROM php:8.3-fpm-alpine RUN apk add --no-cache \ bash curl libpng libjpeg-turbo-dev libzip-dev oniguruma-dev \ && docker-php-ext-install pdo pdo_mysql zip mbstring WORKDIR /var/www COPY --from=vendor /app /var/www COPY --from=frontend /app/public/build /var/www/public/build RUN chown -R www-data:www-data /var/www USER www-data Use Alpine Images they are much smaller and good for prod. Split the build into stages This keeps dev tools out of the final image. Do not install Composer or Node in the final Image this reduces the size and security risks. Don't use COPY . . at the end copy only what you really need (no .env, .git, tests, etc). A non optimize image can be 1.2GB or more. under 200MB! Use USER www-data at the end Add a .dockerignore file node_modules vendor .env .git tests Optimized Docker images are faster, safer, and cheaper. Have youy optimized you Laravel Setup ?

I just read a performance benchmark that broke my understanding of what's possible in web development. Not because the numbers were good—but because they were so impossibly good that I had to read them three times to believe they were real. Traditional React App: 2.3 seconds to interactive Vue.js Application: 2.1 seconds to interactive Juris (Fine-Grained): ~5 milliseconds to interactive Juris (Batch Mode): ~4.5 milliseconds to interactive That's not a typo. Five milliseconds. For a complex dashboard application. That's not 10% faster than React. That's not even 10x faster. That's 400-500x faster. And when I dug into how this was possible, I realized we've been fundamentally approaching web application architecture wrong for over a decade.

I think we're about to miss the biggest shift in web development since React. Not because it's happening too fast, but because it's happening too quietly. Because it looks too simple. Because it challenges too many assumptions we've built our careers on. Let me show you what I mean. For the past decade, we've accepted a fundamental trade-off in web development: Simple = Limited. Want to manipulate the DOM directly? Use jQuery, but forget about component architecture, state management, or reactive updates. Powerful = Complex. Want components and reactivity? Use React/Vue, but accept the build tools, compilation steps, bundle analyzers, and cognitive overhead that comes with it. We've normalized 15-step build processes. We've accepted that "Hello World" requires a dozen dependencies. We've c…  ( 7 min )

As a junior pursuing a degree in Computer Science and Technology, my programming endeavors often felt like an interminable cycle of "waiting." I'd wait for compilations to finish, for tests to run, and particularly when dealing with network requests and high concurrency in my course projects, the sluggish responses would make me question everything. My roommates shared these frustrations, often wondering aloud why our seemingly simple projects were so slow to respond. Then, I stumbled upon a framework, a piece of what felt like "black technology," that completely reshaped my understanding of web backend development.

I recently stumbled upon something that made me question everything I thought I knew about DOM manipulation. It started with a simple request: "Can you help convert this to jQuery to see how long the code would be?" What I discovered wasn't just about line count—it was about two fundamentally different philosophies of web development that couldn't be more different in their approach to the same problem. Here's the code I was asked to convert. It's written in a framework called Juris: juris.enhance('.data-table', (ctx) => ({ // Header cells become sortable 'th[data-column]': { className: (el) => () => { const column = el.dataset.column; const sortColumn = ctx.getState('sort.column'); const sortDirection = ctx.getState('sort.direction'); let classes = 'sortab…  ( 6 min )

Introdução A ideia de armazenar programas na memória junto com os dados que eles manipulam é amplamente atribuída a Von Neumann, cuja arquitetura se tornou a base dos computadores modernos. No entanto, conforme os programas cresceram em complexidade, tornou-se essencial desenvolver novas formas de organização do código, dando origem a diferentes modelos de programação. Essa arquitetura inicial possuía uma estrutura mínima, composta por registradores — pequenas áreas de armazenamento dentro da unidade de processamento que guardam temporariamente dados e instruções em alta velocidade — e unidades de memória, responsáveis por armazenar um volume maior de informações temporárias, mas com acesso relativamente mais lento. Essa estrutura era suficiente para programas pequenos, mas, sem uma orga…  ( 7 min )

A recent comment on one of my earlier articles made me write this. Non-English articles on DEV Gabor Szabo ・ Jan 1 '23 #discuss #meta #languages Because of the lack of right-to-left (RTL) support I'd probably not use DEV to publish in any of the RTL languages. That is Arabic, Hebrew, and Persian. Instead I'd use one of the Static Site Generators that support RTL and GitHub pages or GitLab pages for free hosting. The only cost is the domain name, if you'd like to have your own. I personally use mdbook (and another home-made system) to build my own sites/books. here you can see examples of public mdbooks in various languages. You can also see them grouped by language. Then you might also want to cross-post here if you feel the audience here will be interesting, but I am not sure if the few non-English posts will be even found by the right audience.  ( 3 min )
